Price ---------------- quantity
Gourmet coffee $9.00 ---------------- x pounds
Cheap brand $3.00 ------ 20 - x pounds
Mixture $7.50 ---------------- 20
Total 20 pounds
9 x + 3 ( 20 - x ) = 150
9 x + 60 - 3 x = 150
9 x - 3 x = 150 - -60
6 x = 90
/ 6
x = 15 pounds $9.00 Gourmet coffee
5 pounds $3.00 Cheap brand
