The manager of a store that specializes in selling tea decides to experiment with a new blend. She will mix some Earl Grey tea that sells for $4 per pound with some Orange Pekoe tea that sells for $2 per pound to get 600 pounds of the new blend. The selling price of the new blend is to be $3.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types. How many pounds of the Earl Grey tea and Orange Pekoe tea are required? The blend should have pounds of Earl Grey and pounds of Orange Pekoe.

Solution

let

Earl Grey = x pounds

Orange Pekoe =(600-x) pounds

Set up equation as

x *4 + (600-x)*2 = 600*3.50

4x + 1200 -2x =2100

2x=900

x=450

Thus,

Earl Grey = 450 pounds

Orange Pekoe =150 pounds
