Question

Bolivian coffee sells for $4.59 per pound, and Columbian coffee sells for $5.95 per pound. How many pounds of each coffee should be mixed to produce 4000 pounds of a mixture that will be sold for $5.10 per pound?

I think this is a system of equations but I'm not sure. If so, how would you set it up?

Answer 1

B*4.59 + C*5.95=(4000)*5.10

B+C=4000

Answer 2

2500
