Answer:

R(t)=10t^3+3t^2+3t+54

Step-by-step explanation:

The Number Sold since 2013, N(t) = 5t + 9

Price per system, P(t) = 2t^2- 3t + 6

Revenue = Number of System Sold X Price per system

=N(t)XP(t))

= (5t + 9)(2t^2- 3t + 6)\\$Distribute\\=5t(2t^2- 3t + 6)+ 9(2t^2- 3t + 6)\\=10t^3-15t^2+30t+18t^2-27t+54\\=10t^3-15t^2+18t^2+30t-27t+54\\R(x)=10t^3+3t^2+3t+54
