Question

A candy store owner has 50 pounds of candy that he sells for 15 cents per pound. He wishes to mix it with candy that he sells for 65 cents per pound so that the total mixture can be sold at 40 cents per pound. How much of the 65-cent candy should he add?

Answer 1

Candy-1 sells at 15 cents per pound

Candy-2 sells at 65 cents per pound

Mixture of Candy-1 and Candy-2 sells at 40 cents per pound

The average of Candy-1 and Candy-2 is (15+65)/2= 40

Therefor half pound Candy-1 and half pound Candy-2 can be sells at 40 cents per pound

Therefore same pound of Candy-2 should be mixed with Candy-1 i.e 50 pounds.

Answer - 50 pounds of 65 cents per pound candy should be mixed with 50 pounds of 15 cents per pound candy
