Question

Find the cost per pound of coffee mixture made from 8 pounds of coffee that cost $9.70 per pound in 14 pounds of coffee that cost $5.30 per pound?

Answer 1

The total amount of the new coffee mixture would be:

8 + 12 = 20 (pounds)

The price of 20 pounds of coffee mixture would be:

8(9.2) + 12(5.5) = 139.6 (dollars).

Therefore, the average price would be:

139.6/20=6.98 (dollars).

Answer: $6.98 per pound.
