Answer:

$2502.60

Explanation:

The formula for the amount of an annuity due is ...

A = P(1 +r/n)((1 +r/n)^(nt) -1)/(r/n)

where P is the monthly payment (100), r is the annual interest rate (.04), n is the number of compoundings per year (12), and t is the number of years (2). Given these numbers, the formula evaluates to ...

A = $100(1.00333333)(1.00333333^24 -1)/0.00333333

= $100(301)(0.08314296)

= $2502.60

_____

This value is confirmed by a financial calculator. The given answer choices all appear to be incorrect. The closest one corresponds to an annual interest rate (APR) of 4.286%, not 4%.
