20857.65

20857.65

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 18, 896$ , $r = 10 %$ , $n = 4$ , $t = 1$ .

Compute period rate and exponent: $\frac{r}{n} = 0.025$ , $n t = 4$ , so the growth factor is $1.1038128906$ .

Multiply principal by growth factor: $18, 896$ × $1.1038128906$ = $20857.65$ .
