A non toxic floor wax anc be made from lemon juice and food grade linseed oil. The amount of oil should be twice the amount of lemon juice. How much of each ingridient is needed to make 45 ounces of floor wax?

Let X represent the number of ounces of lemon juice and y the number of ounces of linseed oil.

y = 2x

x + 2x = 45

3x = 45

x = 15 ounces of lemon juice

y = 2x = 30 ounces of linseed oil
