Work Step by Step

The relationship is between the number of snacks purchased and the total cost. If 0 snack is purchased then the cost is 18. If 1 snack is purchased, then the cost is 21. If 2 snacks are purchased, the cost is 24. If 3 snacks are purchased, then the cost is 27. We can see a pattern in the range that each cost term is separated by 3 so we can assume that each snack costs 3.00.
