Problema Solution
Pepperidge Farm® Goldfish is a snack food for which 40% of its calories come from fat. Rold Gold® Pret zels receive 9% of their calories from fat. How many grams of each would be needed to make 620 g of a snack mix for which 15% of the calories are from fat?
Answer provided by our tutors
let x grams of goldfish
let y gram of pret
40*x/100+9*y/100= 15*620/100
40x+9y= 9300
x+y =620
9x+9y=5580
31x= 3720
x= 120
y=620-120 =500
