For this case the total change is given by the following relationship:
Total change = Amount of money - Total costs.
Amount of money = $ 32
The total costs are given by the sum of each purchase.
We have then:
Total costs = 4 + (3 * 2) + 5 + 15
Total costs = 4 + 6 + 5 + 15
Total costs = $ 30
Substituting values we have:
Total change = 32 - 30
Total change = 2 $
