The formula for annual compound interest is A=P(1+r/n)^nt where A is the future value of the loan. P is the amount that you first put in. R is the annual interest rate. N is the number of times that interest is compounded per year and T equals the length of the loan/investment. If you were saving money. For college then this would be a good way to go but if you were taking money out as a loan then you would end up paying more. A government subsidized loan is money that The government will give you if you're eligible it is almost like financial aid. Bank won't you take out of the bank and every month they charge you interest on you how much you take out based on a percentage so in the end you end up paying more based on how much you take out and how long it takes you to pay it back.

The moon is roughly 15 billion inches away from earth and the paper that we used is .005 inches thick, the number of folds it would take to reach the moon would be 1.5 times 10 to the 10. This is unrealistic due to the fact that paper cannot be folded that many times. To find this answer I made the thickness of the paper.005 times two to the nth power equal to 15 billion which roughly how far away the moon is.
