A store sells regular coffee for $4 a pound and gourmet coffee for $7 a pound to
get rid of 40 pounds of gourmet coffee the shopkeeper plans to make a blend to
sell for $5 a pound how many pounds of reg coffee should be used?
The  40   pounds of gourmet coffee is worth $7×40 = $280
The   x   pounds of regular coffee is worth          $4x
--------------------------------------------------------
The x+40  pounds of mixed coffee is worth       $5(x+40)

  

280 + 4x = 5(x+40)

Solve that and get x=80 pounds of regular coffee.
