The Candle Supply Store sells votive wax for $.90 a pound and low-shrink wax for $1.04 a pound. How many pounds of low shrink wax should be mixed with 8 pounds of votive wax to obtain a blend that sells for $.98 a pound?
Answer provided by our tutors
let
x = the pounds of low shrink wax
cost of 8 lbs of votive wax by $0.90 per lbs + cost of x lbs of low shrink wax by $1.04 per lbs = (x + 8) lbs mix by $0.98 per lbs
0.90*8 + 1.04*x = 0.98*(x + 8)
by solving the equation we find
x = 32/3
x = 10.67 lbs approximately
We should use 10.67 lbs of low shrink wax to make the mix.
