Answer:
$1,701.64
Step-by-step explanation:
(see attached for reference)
recall that for compound interest, the following formula applies:
A = P [1 + (r/n) ] ^ (nt), where
A = final amount (we are asked to find this)
P = Principal amount = $1,200
r = interest rate = 5% = 0.05
t = 7 years
n = 12
Substituting these into the equation,
A = 1200 [1 + (0.05/12) ] ^ [(12)(7)]
A = $1,701.64
Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:
![I=p+prt\\I=(500)+(500)(0.2)(2)\\I=500+200\\I=700](https://tex.z-dn.net/?f=I%3Dp%2Bprt%5C%5CI%3D%28500%29%2B%28500%29%280.2%29%282%29%5C%5CI%3D500%2B200%5C%5CI%3D700)
So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.
