Question

2. One gram of fat contains 9 calories, and one gram of protein contains 4 calories.

If one serving of a food contains 170 calories and has 6 grams of protein, which
equation can be used to find the number of grams of fat, x, in the serving?
A. 6x + 36 = 170
B. 9x+ 24 = 170
C. 7(x + 9) = 170
D.13(x + 6) = 170

Answer 1

B.9x+24=270

Explanation:

The answer is B because 6 times 4 is 24, referring to amount of protein grams, and we do not know how many grams of fat there is thus 9 is 9x(to find out how many grams there are in total).
