A business is choosing between six potential repeatable options, $1$ through $6.$ Option $j$ costs

$$10,000j$ to set up$,$ and returns $$(1000+220j+30j^2-6j^3)$ at the end of each year for $j+1$

years. After $j+1$ years, location $j$ can be salvaged for $$1,000-$$$150j.$ If your minimum

acceptable rate of return is $4\%$ and inflation is $2\%,$ which option is best using IRR?
