Anna is making a fertilizer mix for her flower garden. She uses 2 cups of fertilizer to 12 quarts of water. How much fertilizer does Anna need to make 15 gallons of the mixture?

A.

212 cups

B.

5 cups

C.

2212 cups

D.

10 cups

D) 10 cups

Step-by-step explanation:

Since 4 quart = 1 gallon, multiply 4 by 15 to get 60 because there are 15 gallons.

Then, you divide 60 by 12 to get 5 because every 2 cups of fertilizer, 12 quarts of water is used.

Finally, multiply 5 by 2 because Anna uses 2 cups of fertilizer for every 12 quarts of water.

That's how you get the answer of 10 cups.
