The correct answer is:
140 + 16x = 180 + 20x ; x = 10
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.
ANSWERS140+16x=180+20x ; x=10 140 plus 16 x equals 180 plus 20 x ; x equals 10 180+16x=140+20x ; x=−10 180 plus 16 x equals 140 plus 20 x ; x equals negative 10 180−20x=140−16x ; x=20 180 minus 20 x equals 140 minus 16 x ; x equals 20 180−20x=140−16x ; x=10 180 minus 20 x equals 140 minus 16 x ; x equals 10
