Question

Gabriel is at the grocery store and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Which expressions would represent his total cost? Check all that apply.

1. 4.5xy

2. x + 1.5x+ 2y

If y = cost of lettuce per bag, 2 bags of lettuce = 2y

So total cost = 2.5x + 2y
