Daily Dilemma #14: Answer Key

 

  1. #1 shows the cake divided into an equal number of pieces. Each girl will get 4 pieces of cake.

  2. $30.00 / day • 7 days = $210.00
    $.22 / km • 230 km = $50.60 mileage
    total cost = 210.00 + 50.60 = $260.60

  3. Profit = 38.10 – (12.00 + 6.33 + 2.46 + 4.50) = 12.81
    Each boy gets $12.81 ÷ 3 = $4.27
