supermarket, but the cost is a little more at $2.10 per pound. You spend about $3 on gas every time you go to the specialty store. How do you know if you are getting enough of the jelly beans to make the trip worthwhile? What two equations would you use to determine your break-even point? (Let C stand for the total cost and x represent the amount of jelly beans.) a. C = 3.00 + 1.30 x. C = 2.10 x b. C = 3.00 + 2.10 x. C = 1.30 x c. C = 2.10 x + 1.30 x. C = 3.00 d. C = 3.10 x. C = 3.00
