Answer 2

Answer:

The answer is $9669.65 ≈ $9670.

Step-by-step explanation:

The formula to be used is :

$A=P(1+r)^{nt}$

For first part :

p = 7800

r = $5.2/100/12=0.00433$

t = 5

$A=7800(1.00433)^{5}$

A = $7970.04

For second part:

p = 7970.04

r = $33.6/100/12=0.028$

t = 7

$A=7970.04(1.028)^{7}$

A = $9669.65

So, the answer is $9669.65 ≈ $9670.
