Question

Ellen wishes to mix candy worth $1.64 per pound with candy worth $3.46 per pound to form 20 pounds of mixture worth $3.00 per pound. How many pounds of the more expensive candy should she use?

Answer 1

let the amount of expensive candy be x pounds
then the amound of cheaper candy would be 2-x pounds

solve for x:

3.46x + 1.64(20-x) = 3.00(20)
I suggest multiplying each of the three terms by 100

Answer 2
