A project requires $10,000 as initial investment and will earn a revenue of $2,000 per year over the next seven years. The interest rate is 5% per year. What is the present worth of the project's Cost?

A)$1,573

B)$2,000

C)$8,681

D)$10,000

E)$11,573

I use Present worth = - First cost + Annual savings = - $10,000 + $2000 (P/A,5%, 7 years) = - 10,000 + 2,000(5.7786) = $1,573

The solution says D)$10,000 and I'm not sure why. Is it asking for, "what is the first cost"?
