Answer 3

value*

Answer 4

Answer 5

the answer is 15

Answer 6

@jeremydaigle101 Do not give direct answers. In any case, you are wrong.

Answer 7

almost. It's 3% remember, which is 0.03

Answer 11

Oh right!

Answer 12

Oops, I think I did the variables wrong. hold on

P = principal = 50
r = rate = 0.03

Answer 15

n = number of years. My mistake was I made the principal the input, but it's actually the amount of years

Answer 16

f(n) = 50(1 + 0.03)^n?
