122219.36

122219.36

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 9, 412$ , $r = 12 %$ , $n = 2$ , $t = 22$ .

Compute period rate and exponent: $\frac{r}{n} = 0.06$ , $n t = 44$ , so the growth factor is $12.9854819127$ .

Multiply principal by growth factor: $9, 412$ × $12.9854819127$ = $122219.36$ .
