8566.66

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 4, 719$ , $r = 15 %$ , $n = 12$ , $t = 4$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0125$ , $n t = 48$ , so the growth factor is $1.8153548531$ .

Multiply principal by growth factor: $4, 719$ × $1.8153548531$ = $8566.66$ .
