Solution - Compound interest (basic)

35221.70

35221.70

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 21, 949$ , $r = 12 %$ , $n = 4$ , $t = 4$ .

Compute period rate and exponent: $\frac{r}{n} = 0.03$ , $n t = 16$ , so the growth factor is $1.6047064391$ .

Multiply principal by growth factor: $21, 949$ × $1.6047064391$ = $35221.70$ .
