Acoffee company wants a new flavor of cajun coffee. how many pounds of $11 a pound coffee should be added to 30 pounds of coffee worth $3 a pound to get a mixture worth $5 a pound?

Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
