I'll call the quantity of RV x. Then the quantity of Kona Blend will be 10-x
:
8.60x+13.20(10-x) = 12.74(10)
8.60x+132-13.20x = 127.40
-4.60 = -4.60
x = 1 You need 1 pound of 8.60 and 10-1= 9 pounds of 13.20
------------------------------
Check:
1 lb at 8.60 = 8.60
and 9 lbs at 13.20 = 118.80
8.60+118.80 = 127.40 and 127.40/10 = 12.74 per pound. Correct.
