Question 604601: confuse how to get the equation need help , Microwave popcorn has 125 calories and 3g of fat. A serving of chocolate chips has 70 calories and 4g of fat. How much of each should be mix to make a treat that has 255 calories and 24.6 grams of fat?

Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
it is a system of equations that you solve by substitution or elimination

125m + 70c = 255 ___ multiplying by 2 ___ 250m + 140c = 510

3m + 4c = 24.6 ___ multiplying by 35 ___ 105m + 140c = 861

subtracting the equations will eliminate c

solve for m, and substitute back to find c
