71646.69

71646.69

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 9, 321$ , $r = 8 %$ , $n = 2$ , $t = 26$ .

Compute period rate and exponent: $\frac{r}{n} = 0.04$ , $n t = 52$ , so the growth factor is $7.6865887073$ .

Multiply principal by growth factor: $9, 321$ × $7.6865887073$ = $71646.69$ .
