Verified step by step guidance1
Start by identifying the conversion factors needed to solve the problem. We know that 1 quart = 2 pints, 1 pint = 2 cups, and 1 cup = 8 fluid ounces.
Convert fluid ounces to cups. Since 1 cup = 8 fluid ounces, divide the total fluid ounces (160) by 8 to find the number of cups.
Convert cups to pints. Since 1 pint = 2 cups, divide the number of cups obtained in the previous step by 2 to find the number of pints.
Convert pints to quarts. Since 1 quart = 2 pints, divide the number of pints obtained in the previous step by 2 to find the number of quarts.
Review the conversion steps to ensure accuracy and verify that the final number of quarts matches one of the provided answer choices.
