Solution - Compound interest (basic)

15121.22

15121.22

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 9, 303$ , $r = 7 %$ , $n = 4$ , $t = 7$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0175$ , $n t = 28$ , so the growth factor is $1.625412896$ .

Multiply principal by growth factor: $9, 303$ × $1.625412896$ = $15121.22$ .
