Step-by-step explanation:
Calculation for How many pounds of regular coffee should he use
Let pounds of regular coffee be x
Let value of regular coffee be 5x
Let cost of gourmet coffee be 8
Let value of gourmet coffee be 8*30
Let pounds of mixture be 30+x
Let value of mixture be 6(30+x)
Equation:
5x+(8*30)=6(30+x)
5x+240=6(30+x)
Now Let Solve for x:
5x+240=180+6x
240-180=6x-5x
60=1x
x=60/1
x=60
Therefore, he should use $60 pounds of regular coffee
