Rachel has 30 pounds of a mixture of candy that sells for $1.00/lb. If lollipops sell for $0.95/lb and caramel candies sell for $1.10/lb. How many pounds of lollipops are in the mixture?
1 answer:
L = pounds of lollipop c = pounds of caramel candies 0.95l + 1.10c = 30 ($0.95/lb & $1.10/lb) l + c = 30 (mixture sells for $1/lb) c = 30 - l 0.95l + 1.10(30 - l) = 30 (Substitution) 0.95l + 33 - 1.10l = 30 -0.15l = -3 (move terms) l = 20lbs Hope this helps.
