Kim knows she should keep her fat intake to less than 130 grams per day if on a 4,000 calorie diet. she is on a 1,500 calorie per day diet. how many grams of fat should she limit herself to each day?
a. 4,867 grams
b. 5067 grams
c. 48.7567 grams
d. 86.67 grams

130/4000 = 13/400

13/400 = 0.0325

= 3.25%

Soo.. 3.25% of 1500 is your answer 

This is how I find percentages..
10% of 1500 = 150
So 5% of 1500 = 75
So 2.5% of 1500 = 37.5

since you are looking for 3.25%, find an answer in between 37.5 and 75, eliminating all answers but C.

The answer is C = 48.7567 grams

It is going to be the third choice
