233230.02

233230.02

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 16, 468$ , $r = 15 %$ , $n = 4$ , $t = 18$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0375$ , $n t = 72$ , so the growth factor is $14.1626195105$ .

Multiply principal by growth factor: $16, 468$ × $14.1626195105$ = $233230.02$ .
