A shipping company charges $20 to ship a box of books weighing 75 pounds. Each additional pound increases the cost by $0.40 per pound. Write an equation for the total cost of shipping a box of books, given that the box will weigh more than 75 pounds. Let C represent the cost in dollars and x the number of pounds shipped.
