~~~~~~~~~~~~~~~~~~

x = pounds of coffee type A; 2x = pounds of coffee type B. The total cost equation 4.10x + 5.15*(2x) = 288.00 dollars. Simplify and find x 4.10x + 10.30x = 288 14.40x = 288 x = 288/14.40 = 20. ANSWER. 20 pounds of coffee type A.

This month's blend uses twice as much of B as A, so the blend is 2/3 of B and 1/3 of A.

The price per pound of the blend, using 2 parts of B and 1 part of A, is

Since the total cost of the blend is $288, the number of pounds is 288/4.80 = 60.

One-third of the blend is type A; 1/3 of 60 is 20.

ANSWER: 20 pounds of type A
