Question 1123088: A coffee company wants a new flavor of Cajun coffee. How many pounds of coffee worth $10 a pound should be added to 30 pounds of coffee worth $4 a pound to get a mixture worth $5 a pound? Answer by ikleyn(52797) (Show Source):
Let x = "How many pounds of coffee worth $10 a pound should be added".
Your equation is
cost of the first ingredient + cost of the second ingredient = total cost, or
10x + 4*30 = 5*(x+30)
Simplify and solve for x.
