The cost for a company to produce x smartphones can be modeled by C(x)= 2x+35 and the company's total profit after selling x sma
rtphones can be modeled by P(x)= -x^2+120x-435. which function below represents the company's revenue for selling smartphones? ( recall that profit equals revenue minus cost) A) R(x)= -x^2+122x-400
B) R(x)= -x^2+118x-470
C) R(x)= -x^2+122x-470
D) R(x)= -x^2+122x+400
It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!
