Solution - Compound interest (basic)

9987.76

9987.76

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 7, 859$ , $r = 3 %$ , $n = 12$ , $t = 8$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0025$ , $n t = 96$ , so the growth factor is $1.270868467$ .

Multiply principal by growth factor: $7, 859$ × $1.270868467$ = $9987.76$ .
