Each serving of ice cream weighs 65 grams, contains 160 calories, and 10 grams of fat Maggie wishes to formulate her problem as a linear programming problem She has decided that her decision variables are: SB-the # of servings of snack bars she wil have for dessert IC.the # of servings of ice cream she will have for dessert. Maggie wishes to have no more than 450 calories in her dessert. The constraint that expresses this is: 375B 65 IC 450 o 120 S8+ 160 IC 45o 37SB+65K-.450 Next . F8 F9

Explanation / Answer

ANSWER: 120SB + 160IC <= 450

Each serving of Snackbar (SB) contains 120 calories and each serving of Icecream (IC) contains 160 calories

Therefore, total calories she will have in her dessert = 120*SB + 160*IC

This amount of calories should be less than 450. Therefore Right hand side of the inequality is 450 and the sign is <=

Resulting constraint is

120SB + 160IC <= 450
