Camila wants to buy raspberries and pears to make a fruit tart. Raspberries cost $4 per pound and pears cost $3.25 per pound. How much does she spend if she buys 2.5 pounds of raspberries and 2 pounds of pears? How much does she spend if she buys x pounds of raspberries and y pounds of pears?

Answers

  1. The total cost of raspberries and pears if she buys 2.5 pounds of raspberries and 2 pounds of pears is $16.5.

    Algebra

    • Cost of raspberries per pound =$4
    • Cost of pears per pound = $3.25
    • If she buys 2.5 pounds of raspberries and 2 pounds of pears
    Total cost = (Cost of raspberries × pounds of raspberries) + (Cost of pears × pounds of pears)
    = (4 × 2.5) + (3.25 × 2)
    = 10 + 6.5
    = $16.5
    • if she buys x pounds of raspberries and y pounds of pears?
    Total cost = (Cost of raspberries × pounds of raspberries) + (Cost of pears × pounds of pears)
    = (4 × x) + (3.25 × y)
    = 4x + 2y
    Therefore, the equation that can be used to represent the total cost of raspberries and pears given the cost per pound of raspberries and pears is 4x + 2y.
