Question 5
A firm's revenue function is given by R(x) = 2x^2 + 5x + 1, where x is the number of units produced. If the firm's marginal revenue is 10 when x = 3, what is the value of the firm's total revenue at x = 5?
Question 6

Question 8
A firm's \cost function is given by ( C(q) = 2q^2 + 10q + 5 ). If the firm's revenue function is ( R(q) = 4q^2 - 2q + 1 ), what is the firm's profit-maximizing quantity?
