17743.47

17743.47

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 17, 221$ , $r = 3 %$ , $n = 4$ , $t = 1$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0075$ , $n t = 4$ , so the growth factor is $1.0303391907$ .

Multiply principal by growth factor: $17, 221$ × $1.0303391907$ = $17743.47$ .
