Question

A television video game company has the following total expenses E and total incomes I for producing x number of games.

E=200+11x
I=120+x2
Write an equation to represent the profit p for selling x videos.

Answer 1

Profit=income-expenses
P=(120+x^2)-(200+11x)
Add like terms
P=x^2+11x-80
That is your equation

The answers are x= -16 and 5 but since you can’t sell negative video games, the only possible answer is 6
