You can put this solution on YOUR website!
ethiopian coffee $8.80 -----x lbs
arabian coffee $14.30-------10-x lbx
..
Mix $9.35 -10 lb.-4950
8.8x+14.30(10-x)= 10* 9.35
multiply equation by 100
88x+1430(10-x)=10*935
88x+14300-1430x = 9350
-1430x+88x=9350-14300
-1342x = -4950
x=-4950/-1342
x=3.69 lbs Ethopian coffee
balance will be arabian coffee
