Problema Solution
The U.S. centers for Disease Control recommends that for a typical 2000 calorie daily diet, no more than 65g of fat be consumed. In the first three days of a four day vacation, Teresa consumed 55g, 80g, and 70g of fat. Determine how many grams of fat Teresa consumed on the forth day if she is to average no more than 65g of fat per day
Answer provided by our tutors
The average calorie consumption per day is found by adding the calories of all four days and dividing by four. If teresa is to eat an average of 65g of fat per day, the total calories divided by four should equal 65.
(55+80+70+x)/4 = 65
Adding up and multiplying both sides by 4 gives
205+x=260.
Solve for x by subtracting 205 from both sides.
x=55
