The cash flow are confirmed to be $-$$$3,240,000$ for Year $0,$ $$1,242,003$ for Year $1,$ $$1,309,230$ for Year $2,$ and $$1,724,501$ for Year $3.$ I am struggling to find the NPV with a required rate of return of $10\%$ for these numbers. I am adding them up with the NPV formula and the system still says my answer is wrong.
