Video games sold: X Revenue function: R(x)=60x Cost function: C(x)=12+7x Profit function P(x) = P(x)= 67x+12 67x-12 53x+12 53x-12

The profit function is calculated by subtracting the cost function from the revenue function. In this case, the revenue function is R(x) = 60x and the cost function is C(x) = 12 + 7x. Therefore, the profit function is P(x) = R(x) - C(x) = 60x - (12 + 7x) = 53x - 12. So, the correct answer is $53x-12$.
