2205.64

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 1, 559$ , $r = 7 %$ , $n = 4$ , $t = 5$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0175$ , $n t = 20$ , so the growth factor is $1.4147781958$ .

Multiply principal by growth factor: $1, 559$ × $1.4147781958$ = $2205.64$ .
