A coffee distributor needs to mix a(n) Breakfast coffee blend that normally sells for $8.30 per pound with a Gazebo coffee blend that normally sells for $8.70 per pound to create 70 pounds of a coffee that can sell for $8.33 per pound.

How many pounds of each kind of coffee should they mix?

B + G = 70

B (8.30) + G (8.70) = 70 * 8.33

[B * (8.30)] + [(70 - B) * (8.70)] = 70 * 8.33
