I AM GONNA CRY PLEASE PLEASE HELP ME You invest $5,000 dollars in an account at 1.6% interest and interest is compounded
annually (once a year).
a) Write an equation that shows the amount of money you have after x years.
b) How much money would you have after 15 years?

Part (a)

Explanation:

You use the compound interest formula

A = P(1 + r/n)^(n*t)

where

After plugging those values in, you would go from A = P(1 + r/n)^(n*t) to

A = P(1 + r/n)^(n*t)

A = 5000(1 + 0.016/1)^(1*x)

A = 5000(1.016)^x

Since you're using x for the input, it's possible your teacher wants you to use y for the output. So replace A with y to get y = 5000(1.016)^x

Part (b)

Explanation:

Plug x = 15 into the equation we found back in part (a). Use your calculator to simplify. Round to the nearest hundredth which is rounding to the nearest penny.

y = 5000(1.016)^x

y = 5000(1.016)^15

y = 6344.1818561953

y = 6344.18

the answer is b.)

< 1=< 2

nope.   happens to me as well.
