Question

Brayden, Laney, and Rodney sold World's Finest Chocolate candy bars to help the band raise money to go to Disney at Christmas. Brayden sold 15 candy bars less than Laney. Rodney sold twice as many candy bars as Laney. If they sold one hundred thirteen candy bars total, how many boxes did each student sell?

Answer 1

Answer: Laney = 24.5, Brayden = 9.5, Rodney = 49

Explanation:

Define Variables: Laney = x, Brayden = x-15, Rodney = 2x

Set up equation: x + x-15+2x = 113

Combine Like Terms: 4x + 15 = 113

Solve: 4x = 98 --> x = 24.5

Plug 24.5 back into original variables

Laney = 24.5, Brayden = 24.5-15=9.5, Rodney = 49
