20198.57

20198.57

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 1, 910$ , $r = 14 %$ , $n = 1$ , $t = 18$ .

Compute period rate and exponent: $\frac{r}{n} = 0.14$ , $n t = 18$ , so the growth factor is $10.5751691843$ .

Multiply principal by growth factor: $1, 910$ × $10.5751691843$ = $20198.57$ .
