Question

value: 1
a man who consumes 2,500 calories per day wants to consume less than the maximum of 35% of calories from protein. how many grams of protein would this be?
a. 75 grams
b. 112 grams
c. 188 grams
d. 218 grams

Explanation:

Step1: Calculate calories from protein

First, find 35% of 2500 calories. The formula for percentage is $ \text{Percentage of total} = \frac{\text{Percentage}}{100} \times \text{Total} $. So, $ 0.35 \times 2500 = 875 $ calories from protein.

Step2: Convert calories to grams of protein

Protein provides 4 calories per gram. So, to find grams, use the formula $ \text{Grams} = \frac{\text{Calories from protein}}{\text{Calories per gram of protein}} $. Thus, $ \frac{875}{4} = 218.75 $, but since we want less than the maximum, we check the options. Wait, actually, maybe I made a mistake. Wait, no—wait, the question is "less than the maximum of 35%", but let's recalculate. Wait, 35% of 2500 is 875 calories. Protein is 4 cal/gram, so grams = 875 / 4 = 218.75. But the options have 218, which is close (maybe rounding). Wait, but let's check the options again. Wait, maybe I messed up. Wait, no—wait, the options: a.75, b.112, c.188, d.218. Wait, maybe I did the percentage wrong? Wait, no, 35% of 2500 is 875. 875 divided by 4 is 218.75, so the maximum grams would be approximately 218 (since it's less than the maximum, but the calculation for the maximum is 218.75, so the answer is d? Wait, no, wait—wait, maybe the question is "less than 35%", but the calculation for the maximum grams (at 35%) is 218.75, so the answer is d.218 grams. Wait, let's recheck:

Step 1: Calculate 35% of 2500 calories: $ 2500 \times 0.35 = 875 $ calories.

Step 2: Since 1 gram of protein = 4 calories, grams of protein = $ \frac{875}{4} = 218.75 $, which is approximately 218 grams (option d).

Answer:

d. 218 grams
