You sold 52 boxes of candy for your marching band fundraiser. The large size box costs $3.50 each and the small size box costs $1.75 each. If you sold $112.00 worth of candy, how many boxes of each size did you sell?

Let x = # larger box

  then 52 - x = # smaller boxes

 

3.50 * x    +   1.75 * (52-x) = 112

3.5x - 1.75x + 91 = 112

1.75x = 21

x = 12 = # larger boxes       52-12 = 40 = # smaller boxes
