Shawna opens a bank account with $400. The account accrues 8% interest compounded annually.

How much money, to the nearest cent, will she have in her account at the end of 4 years? (Use the formula A=P(1+rn)nt, where P= initial amount of money, r = interest rate, t = the number of years, and n = number of times the interest is compounded per year.)

A = 400 * (1 + (1 * 0,08)) * 1 * 4

You juste have to calculate... I think!

Almost but not quite Sam

P is the principle = 400
r=0.08 and n=1 because it accrues just once a year.
t=8 because it is 8 years

The formula is not A=P(1+rn)nt it is A=P(1+rn)^(nt) or A=P(1+rn) ^nt

To get the nt up in the air, I highlighted it and then pressed 'sup' which is found above the smilies. sup stands for superscript.

A = 400*(1+0.08) ⁴ ==> 400*1.08 ⁴
