Help with simple and compound intrest! plz help! due 2maro.?
hi! my teacher does a part of a chapter each day like to day wuz 3.8 yesterday wuz 3.7, b4 tat 3.6. and there is not enough time to review much or anything so please help! its 1-16!!!!! find the amount of the simple interest earned for #'s 1 through 8 1) principal: $620 annual rate: 3.5% time: 2 yrs. 2) principal: $500 annual rate: 6.5 time: 32 months 3) principle: $750 annual rate: 3.5% time: 18 months 4) principal: $2000 annual rate: 4% time: 5 yrs. for an account that earns simple annual intrest, find the balance of the account. this might help!: I = prt I= intrest P= principle R= intrest rate T= time in years (not months) 5) P=$400,r = 3%,t=6 years 6)p=$950, r =4.5,t = =5 yrs. 7) p= $1500,r=2%,t = 4months 8)p = $2400, r = 3.25 t,= 5 years 9 -13 needs to be a COMPOUND INTREST 9) principle $1200 annual rate: 4% time: 3 years 10) princible: $3500 annual rate: 3.6% time: 54 months 11) principal: $840 annual rate: 2.75% time: 3 yrs. 12) principal: $1550 annual rate: 5.8 time: 54 months 13) you deposit $700 in a saving account that pays 4.2% simple annual interest. how much will you have in you account after 63 months? 14) on january 1st, a credit card has a balance of $680 the credit card company charges an interest rate of 18.5% compounded annually. if no payment or purchases are made, what is the balance on febuary 1st? 15) the account below earn intrest compounded annually. which account will have the greater balance in the given time? explain your reasoning. Account A Account B principal:$350 principal: $350 annual rate: 2.25% annual rate: 4.5 time: 20 yrs. time: 10 yrs. 16) how much money must yu deposit into a savings account that pays 4.8% simple annual intrest to have a balance of $1850 after 10 yrs? please, this is weird but when summiting your answer, please do NOT show your work! and please do this: 1. your answer 2. your answer ect.... THANKS SO MUCH!!!!
Need help with three math problems dealing with interest?
I was absent from school and am having trouble. I can't understand these four problems in my homework. Any help to solve any of these four questions would be so appreciated! 1. On may 1, you sign a $1000 note with simple interest if 11% and a maturity date of December 19. You make partial payments of $475 on June 2 and $275 on November 4. How much will you owe on the date of maturity? 2. Determine the effective annual yield for $1 invested for one year at 9% compounded monthly. 3. On the October 3 billing date, Violet had a balance due of $871.60 on her credit card. The transactions during the following month were: October 12 Charge: $265.73 October 15 Payment: $335 October 25 Charge: $377.41 The interest rate on the card is 1.7% per month. Using the unpaid balance method, find the finance charge on November 3.
Interest math problem?
You have a choice of two accounts in which to invest your money for one year. Account A pays 6.8% simple interest, and Account B pays 6% compounded monthly. Compute the effective annual yield of Account B and determine which account has the better rate. This is not a homework problem, so please don't tell me to do my own homework. It is a problem on a math test that I got wrong. Please show your work. I got the correct answer, but their were flaws in my work.
Mathematical formula for compounded interest?
A = p (1+r/n) ^ nt A = amount p = principal r = rate n = number of times a year it is compounded t = time in years edit: sorry; I had I instead of A. It is definitely A!!!!! I am very sleepy and should probably go to bed now. Hope I didn't mess you up. Thanks enrico!
DAVE- Can you help me with Math! Or someone!?
Use for 1-5, and 10 A= P(1 + r/n)^(n*t).....A= amount and interest, P= principle (original $) ...................................r= interest rate as a decimal, t= time in years ..................................n= number of compound periods per year n= 1 for simple annual interest n= 4 for quarterly compounds n = 12 for monthly compounds Use for 6,and 9 A = Pe^(rt) for continuous compounding Here is a site to help you with the rest: http://mathforum.org/dr.math/faq/faq.int...
Grade 11:I need help with annuities?
This question is from my grade 11 functions textbook: Greg borrows $123 000 for the purchase of a house. He plans to make regular monthly payments over the next 20 years to pay off the loan. The bank is charging Greg 6.6%/a compounded monthly. What monthly payments will Greg have to make? The formulas in my textbook are: FV = R/i [(1+i)^n -1] ; A = P(1+i)^n FV = future value R = regular payment i = interest rate per compounding period n = # of payment periods A= total amount P= principal (the original investment) Before anyone says to do my homework myself, i would just like to say that i have tried. I just don't seem to be able to get the right answer with the ones with bank loan. I can get the right answers for the ones where I'm investing money and my net value is increasing, but in loans the value is decreasing. I think it has to do with the fact that i don't know what to place as the ' i ' variable. When it's increasing ' i ' is easy to determine. You just take the annual rate and divide by the payment periods for the year.
Are there disadvantages to having a degree in math and working as a programmer? If so, what are they?
Yes, there are disadvantages. The most important one is that you will probably be bored. Software development has strong ties to engineering, because of history. In short, engineers like to think about what a computer is doing, and write programs as sequences of steps to manipulate what the computer is doing into solving your problem. But that is often a terrible way to solve a problem.Similarly, you will have problems communicating with others. "Data structures" is very similar to abstract algebra, in the sense that you are building objects out of component parts, and then figuring out how to query them (and what you can actually get out of them). You will be tempted to use vocabulary like "lattice of relations" or "homomorphism" or even "functor," but you will get vacant stares.Object orientation is an awful abstraction. Sure, the idea of little machines doing computation independently of the others is great. Objects do good things, like separating state and making it easier to reason about a program. But almost every object oriented language forces a class system on you. Which means bending over backwards to implement things that ought to be really simple. Like functors, with the factory patterns.Worse still, because people read it out of a book, they think their patterns are more maintainable than the obvious thing, like defining a operator that takes a function as an argument.And if you don't know this now, let me introduce another disadvantage: you could be making a lot more money in business. A lot more. Even though it will still be "work" and has its own frustrations, you will get more out of it.
