Solution - Compound interest (basic)

25739.90

25739.90

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 2, 985$ , $r = 9 %$ , $n = 1$ , $t = 25$ .

Compute period rate and exponent: $\frac{r}{n} = 0.09$ , $n t = 25$ , so the growth factor is $8.6230806604$ .

Multiply principal by growth factor: $2, 985$ × $8.6230806604$ = $25739.90$ .
