The Cupcake Cafe makes 4 1/2 times as much revenue on doughnuts as muffins. If the total sales was $44,000 for May, what dollar amount of each was sold?

  • Math -

    then figure donut revenue

  • Math -

    Represent the unknowns with variables.
    Let x = total amount of Muffins sold in dollars
    Let (4 1/2)x = total amount of Doughnuts sold in dollars (according to the first statement)
    Then we set up the equation. Since their total is $44,000:
    x + (4 1/2)x = 44000
    Then we solve for x. We first convert the mixed number (the 4 1/2) to improper fraction. 4 1/2 = ((4 x 2) + 1)/2 = 9/2.
    (x + (9/2)x = 44000) x 2
    2x + 9x = 88000
    11x = 88000
    x = $ 8,000 (Muffins)
    (9/2)x = $ 36,000 (Doughnuts)

    Hope this helps~ :3
