Price ---------------- quantity
Premium coffee $6 ---------------- x pounds
Regular coffee $4 ------ 100 - x pounds
Mixture $4.64 ---------------- 100
6 x + 4 ( 100 - x ) = 4.64 * 100
600 x + 400 ( 100 - x ) = 46400
600 x + 40000 - 400 x = 46400
600 x - 400 x = 46400 - -40000
200 x = 6400
/ 200
x = 32 pounds $6.00 Premium coffee
68 pounds $4.00 Regular coffee
