Question

One serving of havarti cheese has 110 calories. Assume all the calories in the cheese are from fat and protein. That provides 9 calories per gram, and protein provides 4 calories per gram. The combined mass of the fat and protein in the serving of cheese is 15 grams. How many grams of protein are in the serving of cheese?

A. 7.5 grams
B. 10 grams
C. 11 grams
D. 15 grams

Answer 1

To find out how many grams of protein are in a serving of havarti cheese, we can use the calorie content and the calories per gram of fat and protein. By subtracting the calories from fat from the total calories, we can determine the calories from protein, and then convert that into grams of protein using the calorie-to-gram ratio.

Step-by-step explanation:

To find out how many grams of protein are in a serving of havarti cheese, we need to understand that the total mass of the fat and protein is 15 grams. Since every gram of fat and protein provides 9 calories, the total calories in the serving of cheese will be 15 grams x 9 calories/gram = 135 calories. Since we know that 110 calories in the serving come from the cheese, the remaining calories must come from protein. Therefore, the number of grams of protein in the serving of cheese is 135 calories ÷ 4 calories/gram = 33.75 grams.
