an ice cream shop makes vanilla and chocolate ice cream. the vanilla ice cream machine has a 180 cup capacity, and it sells 20 cups per day. the chocolate ice cream machine has 140 cup capacity, and it sells 16 cups per day. write and solve an equation to show when the two machines will have the same amount of ice cream left
180 + 16x = 140 + 20x ; x = -10
140 + 16x = 180 + 20x ; x = 10
180 - 20x = 140 - 16x ; x = 10
180 - 20x = 140 - 16x ; x = 20
1 answer
The two machines will have the same amount of ice cream left after 10 days or 20 days.
