Candy worth $1.05 per pound is mixed with candy worth $0.85 per pound to obtain 20 pounds of a mixture
worth $0.90 per pound. How many pounds of each candy are used?

Answer 1

Answer:

value + value = value

1.05x + 0.85(20-x) = 0.90*20

105x + 85*20 - 85x = 90*20

20x = 5(20)

x = 5 lbs (amt. of $1.05 coffee needed)

-----

20-x = 15 lbs (amt. of $0.85 coffee needed)
