Amy Sims runs an advertisement firm. She estimates that a \(\$ 7,000\) high-resolution printer will result in increased cash inflows of \(\$ 2,000\) in year \(1, \$ 4,000\) in year 2 , and \(\$ 4,500\) in year 3 . Amy's cost of capital is \(10 \%\). Calculate the net present value. What is the internal rate of return at this price?
