A man wants to make up 100 one-pound jars of nuts to sell for 66 cents a jar. He plans to use 40 pounds of nuts worth 75 cents a pound. What should be the unit price of the other type of nuts he uses?
Let P be the price of the other 60 lbs of nuts
So we have this
40 (.75) + 60(P) = 100 (.66) simplify
30 + 60P = 66 subtract 30 from both sides
60P = 36 divide both sides by 60
P = 36 / 60 = 6/10 = .60 [ 60 cents ]
