Compute how much a business is worth if it is expected to generate cash flows to its owners of $$0$ for the next two years, $$42,800$ in three years, $$60,000$ in four years, then $$85,000$ per year for the subsequent U years $($i$.$e$.,$ $$85,000$ per year after four years in the future and then continuing for the next U years until $4+$U years into the future$),$ and finally generates cash inflows to its owners of $$100,000$ per year thereafter forever $($i$.$e$.,$ $$100,000$ forever after $4+$U years$),$ assuming that businesses with similar relevant risk have expected returns of $14\%.($U$=20)$
