18839.07

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 15, 127$ , $r = 1 %$ , $n = 2$ , $t = 22$ .

Compute period rate and exponent: $\frac{r}{n} = 0.005$ , $n t = 44$ , so the growth factor is $1.2453938515$ .

Multiply principal by growth factor: $15, 127$ × $1.2453938515$ = $18839.07$ .
