My online application is saying invalid minimum annual salary, why is it saying this?
I've run into this also. For example the field asks for a minimum annual salary, but it does not give an example of how it wants it typed. So you want $40,000.00 and that's what you type. Maybe the field does not recognize the dollar sign,the comma and the decimal point. Maybe it only wants to see 40000 with no other characters inserted. Try monkeying around with it like I noted and see if that helps. Otherwise raise it up by a 100K and see what happens.
*If hired, can you furnish proof that you meet your state's minimum age requirement?:?
It means do you have a driver's license or state issued photo ID to prove who you are and your age. And the documentation verifying your identity and legal right to work in the US would be your drivers license/state issued photo ID, birth certificate, or Social Security card. Being 16, you should be fine on the minimum working age. If you have any doubt, just do a search on your state's employment age law. Good luck on your first job!
Can a Lincoln Navigator run on Regular Unleaded Gasoline instead of Premium Gasoline? Is there a difference?
Excerpt from 2005 Lincoln Navigator owners manual (page 373): "Octane recommendations Your vehicle is designed to use “Premium” unleaded gasoline with an (R+M)/2 octane rating of 91 or higher for optimum performance. The use of gasolines with lower octane ratings may degrade performance. The use of gasolines labeled as “Premium” in high altitude areas that are sold with octane ratings of less than 91 is not recommended. Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily under most driving conditions while you are using fuel with the recommended octane rating, see your dealer or a qualified service technician to prevent any engine damage."
