The restaurant sold 144 cups of drinks in all.
Steps to Solve
-
Calculate the total quarts in a box A box contains 18 bottles, and each bottle has 2 quarts. Multiply the number of bottles by the quarts per bottle. $$18 \text{ bottles} \times 2 \text{ quarts/bottle} = 36 \text{ quarts}$$
-
Convert quarts to cups There are 4 cups in a quart. Multiply the total number of quarts by the number of cups per quart. $$36 \text{ quarts} \times 4 \text{ cups/quart} = 144 \text{ cups}$$
The restaurant sold 144 cups of drinks in all.

Tips
A common mistake is to confuse the conversion between quarts and cups, or to multiply when you should divide, and vice versa. Remembering that there are 4 cups in a quart can help avoid this mistake.
