Here are three problems about time at the carnival. They are missing some information.
In the blanks, write numbers or times that make sense for the situation in the problem.
Share the numbers and times you chose with your group and explain why they make sense.
A lemonade stand at the fair makes 132 liters of lemonade a day. When Clare and Tyler stopped by the stand, there were 90 liters left.
At the end of the day, there were 56 liters of lemonade left, which the vendor put on sale in 4-liter jugs.
Use the information about the lemonade stand to write a question that could be answered with the
mathematical work shown.
132 - 90 = 42
