Answer:

He can buy 8 bags of chips.

Step-by-step explanation:

first create a equation:

drink's cost + bag of chip's cost(number of chips) = total

2.9 + 1.85x = 17.7

17.7 is the total, 2.9 is the cost of the drink, 1.85 is the cost of a bag of chips, and x is the number of chips.

Solve for x:

2.9 + 1.85x = 17.7

-2.9              -2.9

         1.85x = 14.8

          1.85    1.85

               x = 8

Check:

12.9 + 1.85(8) = 17.7

12.9 + 14.8     = 17.7

              17.7 = 17.7
