Question The menu of a concession stand is shown on the board below. How many different ways can Elli buy 5 items from the menu for exactly $10?

Let C represent the total cost of each deal Let T be the number of trips down the water slide C = 32 for the 1st deal since the cost is the same regardless of how much she rides C = 18 + T for the 2nd deal To find when the two costs are equal set them equal to each other and solve for T 32 = 18 + TT = 14 trips The cost must be $32 since that is the only cost possible for the 1st deal Reply

Let C represent the total cost of each deal

Let T be the number of trips down the water slide

C = 32 for the 1st deal since the cost is the same regardless of how much she rides

C = 18 + T for the 2nd deal

To find when the two costs are equal set them equal to each other and solve for T

32 = 18 + T

T = 14 trips

The cost must be $32 since that is the only cost possible for the 1st deal
