Let x be the number of days it takes for the two machines to have the same amount of ice cream left.
The amount of vanella ice cream left after x days is 180 - 20x cups.
The amount of chocolate ice cream left after x days is 140 - 16x cups.
Setting these two expressions equal to each other:
180 - 20x = 140 - 16x
4x = 40
x = 10
Therefore, it will take 10 days for the two machines to have the same amount of ice cream left.
An ice cream shop makes Vanella and chocolate ice cream. The vanella 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 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?
