49780.87

49780.87

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 19, 869$ , $r = 4 %$ , $n = 12$ , $t = 23$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0033333333$ , $n t = 276$ , so the growth factor is $2.5054542754$ .

Multiply principal by growth factor: $19, 869$ × $2.5054542754$ = $49780.87$ .
