41735.42

41735.42

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 18, 149$ , $r = 7 %$ , $n = 4$ , $t = 12$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0175$ , $n t = 48$ , so the growth factor is $2.2995987244$ .

Multiply principal by growth factor: $18, 149$ × $2.2995987244$ = $41735.42$ .
