Question

Hello I was given this question earlier but didn’t understand thought it would be good to reach out for some help

Answer 1

Profit = Revenue - Cost

Revenue = Q * P

P = 100 - Q/20

C = 0.12Q + 10

Using substitution, we can say that:

`\begin{gathered} \text{Profit = Revenue - Cost} \\ \text{Profit = }(Q* P)-(0.12Q+10) \\ \text{Profit }=Q(100-(Q)/(20))-(0.12Q+10) \end{gathered}`

Both equations used in the region of profit are linear equations because the exponent or degree used is only 1. Therefore, the region of profit is contained within two linear equations. (Option E)
