77214.99

77214.99

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 21, 716$ , $r = 5 %$ , $n = 1$ , $t = 26$ .

Compute period rate and exponent: $\frac{r}{n} = 0.05$ , $n t = 26$ , so the growth factor is $3.5556726879$ .

Multiply principal by growth factor: $21, 716$ × $3.5556726879$ = $77214.99$ .
