Problema Solution
A nut store normally sells cashews for $4.00 a pound and peanuts for $1.50 per pound. In order to sell 90 pounds of peanuts, the manager decides to mix 90 pounds of peanuts with some cashews and sell the mixture for $2.50 per pound. How many pounds of cashews should be mixed with the peanuts to ensure no change in profit?
Answer provided by our tutors
let 'x' represent the pounds of cashews used, then '90+x' represents the final weight of the mixture
2.5(90+x) = 4x + 1.5(90)
solving for 'x' we have x=60
60 pounds of cashews should be mixed with the 90 pounds of peanuts
