At Lincoln Library there are two ways to pay for copying. You can pay 8 cents a copy, or you can buy a plastic card for $4 and then pay 6 cents a copy. Let x be the number of copies you make. Write an equation for your costs for each way of paying. (Express C(x) in dollars.) without card C(x) = with card C(x) = (a) How many copies do you need to make before buying the plastic card is the same as cash?
