word problem help please?
the revenue R, in thousands of dollars for a small business can be modeled by R=t^3-t^2+t+82, where t is the number of years since 1990. In what year did the revenue reach $90,000?

It would be the third year because…
Year 1 R= 1-1+1+82=? It would be 83
Year 2 R= 8-4+2+82=? It would be 88
Year 3 R= 27-9+3+82=? It would be 103
You exchange the year for ‘t’ and so it would be the third year where it breaks 90 in thousands of dollars.
