19540.81

19540.81

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 14, 478$ , $r = 1 %$ , $n = 12$ , $t = 30$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0008333333$ , $n t = 360$ , so the growth factor is $1.3496901794$ .

Multiply principal by growth factor: $14, 478$ × $1.3496901794$ = $19540.81$ .
