Question

The U.S. Center for Disease Control recommends that for a typical 2000-calorie daily diet, no more than 65 g of fat can be consumed.  In the first three days of a four day vacation, Teresa consumed 55 g, 80 g, and 70 g of fat.  Determine how many g of fat she can consume on the fourth day if she is to average no more than 65 g of fat per day.

anonymous · Answer

Let the grams of fat consume on the fourth day be x.

Since average is to be 65,
(55+80+70+x)/4 = 65
55+80+70+x = 260
x = 55
