Mason used 6 quarts of milk to make chocolate ice cream and 4 pints of milk to make peach ice cream. How many cups of milk did mason use?

28 cups

Step-by-step explanation:

There are 4 cups in each quart. This means the chocolate ice cream which used 6 quarts is the same as 6*4 = 24 cups.

There are 2 cups in a pint. This means the peach ice cream which used 4 pints is the same as 2*2 = 4 cups.

Together he used 24 + 4 = 28 cups
