Let x be the number of days passed since the ice cream shop started selling vanilla and chocolate ice cream.
The amount of vanilla ice cream left after x days is: 180 - 20x
The amount of chocolate ice cream left after x days is: 140 - 16x
The two machines will have the same amount of ice cream left when:
180 - 20x = 140 - 16x
Now, solve for x:
180 - 20x = 140 - 16x
180 - 140 = 20x - 16x
40 = 4x
x = 10
Therefore, after 10 days, the vanilla and chocolate ice cream machines will have the same amount of ice cream left.
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 a 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
