Lou wants to make a coffee mixture to sell. He is going to mix Sumatra coffee which costs $2.50 per pound with Columbian coffee
which costs $3.75 per pound. He wants to male 50 pounds of mix and he wants the cost of the mix to be $3.35 per pound. How many pound of each will he need?
To answer this question you need to create 2 equations: S+C=50 2.50S+3.75C=3.35*(50) S=50-C -so now you can plug in S into the second equation 2.50*(50-C)+3.75C=167.5 Now you just need to solve this equation, the final answer will be 34 pounds of colombian coffee and 16 pounds of sumatra coffee
