Colombian coffee beans cost $5.50/lb while Peruvian coffee beans cost $4.25/lb. We want to mix the beans together so as to produce a 40 lb bag costing $4.60/ lb. How many pounds of each type of beans shouold be used ?

Please help and show work

Answer 1

amount of Columbian stuff --- x lbs
amount of Peruvian stuff ----- 40-x lbs

5.5x + 4.25(40-x) = 4.6(40)
