A grocer wants to mix two kinds of coffee.One kind sells for $1.35 per pound, the other sells for 2.65 per pound. He wants to mix a total of 16 pounds and sell them for $2.05 per pound. How many pounds of each kind should he use in the new mix?

Let x be $1.35 per pound coffee and y is $ 2.65 per pound coffee

x + y = 16 (Total)

1.35x + 2.65y = (16)*(2.05) (Price)

Solve the above system to find x and y

Hint: x = 7.4 lbs and y = 8.6 lbs (These values are rounded)

Hope it will help you!
