Answer:
2.5 x + 2y
Explanation:
We know that he bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each.
2.5 pounds of an apple = x dollars.
2.5 pounds of an apple/cost = 2.5 x
2 bag of lettuce = y dollar(s).
2 bas lettuce/cost = 2y
Expression: 2.5 x + 2y
Therefore 2.5 x + 2y would represent his total cost.
