Answer :
Final answer:
To make the mixture, Marcus and Chloe can use any combination of sand and water that adds up to 108 cups.
Explanation:
To determine how much sand and water Marcus and Chloe should use to make the mixture, we can set up a ratio based on the number of cups. Let's say they use x cups of sand and y cups of water. The ratio of sand to water would be x:y. Since they need a total of 108 cups, we can write the equation x + y = 108.
Since we don't have enough information to solve for x and y individually, there are multiple possible values for x and y that satisfy the equation. For example, they could use 54 cups of sand and 54 cups of water, or 36 cups of sand and 72 cups of water. As long as the total cups add up to 108, they can vary the amounts of sand and water.
To summarize, Marcus and Chloe can use any combination of sand and water that adds up to 108 cups. The specific amounts they choose will depend on their preference and the consistency of the sandcastle mixture they want to create.
