Question

Two friends shop for fresh fruit. Elaine buys a watermelon for​ 6.30$ and pounds of cherries. Elena buys a pineapple for ​$4.15 and 4 pounds of cherries. Use the variable p to represent the​ price, in​ dollars, per pound of cherries. Write and simplify an expression to represent how much more spent.

Answer 1

Explanation:

Elaine spent 6.30 + px dollars on her purchase and Elena spent 4.15 + 4p dollars on her purchase. To find how much more Elaine spent, we can subtract Elena's total cost from Elaine's total cost: (6.30 + px) - (4.15 + 4p) = (6.30 - 4.15) + (px - 4p) = 2.15 + (px - 4p) = 2.15 + p*x - 4p. This is the simplified expression for how much more Elaine spent than Elena.
