Answer:

$1512.27

Explanation:

The future value formula for monthly compounded interest is ...

FV = P(1 +r/12)^(12t) . . . . interest rate r for t years

Filling in the given values gives ...

2000 = P(1 +0.04/12)^(12·7) = P(1.003333...)^84 = 1.322513864P

Then the required principal is ...

P = 2000/1.322513864 ≈ 1512.27

The principal needed is about $1512.27.
