Certified Dietary Manager (CDM) Practice Exam

You need 896 ounces of coffee each morning for the trayline. How many gallons do you need?

1. 6

2. 7

3. 8

4. 9

The correct answer is: 7

In order to convert from ounces to gallons, we must divide the number of ounces by 128 (as there are 128 ounces in a gallon). Thus, 896 ounces divided by 128 equals 7 gallons. Choice A (6) would be too low, as it does not account for the additional 16 ounces. Choice C (8) and D (9) would be too high, as they do not account for the fact that 896 ounces is less than a thousand (and thus would not require 8 or 9 gallons). Therefore, choice B (7) is the most accurate and appropriate answer.
