Solution - Compound interest (basic)

66971.00

66971.00

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 7, 779$ , $r = 8 %$ , $n = 12$ , $t = 27$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0066666667$ , $n t = 324$ , so the growth factor is $8.6092038048$ .

Multiply principal by growth factor: $7, 779$ × $8.6092038048$ = $66971.00$ .
