Solution - Compound interest (basic)

25485.06

25485.06

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 21, 095$ , $r = 1 %$ , $n = 1$ , $t = 19$ .

Compute period rate and exponent: $\frac{r}{n} = 0.01$ , $n t = 19$ , so the growth factor is $1.2081089504$ .

Multiply principal by growth factor: $21, 095$ × $1.2081089504$ = $25485.06$ .
