How many pounds of the Earl Grey tea and Orange Pekoe tea are​ required?

Answer 1

Amount Reqiured are

Earl Grey Tea=300 pounds

Orange Pekoe tea =500 pounds

Explanation:

Let amount of Earl Grey tea to mix = y pounds

Total Amount of Mixture = 800 pounds

That is,

Amount of Orange Pekoe tea + Amount of Earl Grey tea = 800

Amount of Orange Pekoe tea + y =800

Amount of Orange Pekoe tea =800-y

Selling Price of Earl Grey tea = $6 per pound

Selling Price of Orange Pekoe tea = $2 per pound

Selling Price of New Blend=$3.50 per pound

The total sales therefore gives:

6y+2(800-y)=3.5*800

6y+1600-2y=2800

4y=2800-1600

4y=1200

y=300

Therefore the amount of Earl Grey tea to mix= 300 pounds

Amount of Orange Pekoe tea =800-y=800-300=500 pounds
