Can anyone help me with this?

Question

A coffee distributor needs to mix a(n) Mexican Shade Grown coffee blend that normally sells for $11.20 per pound with a House coffee blend that normally sells for $13.50 per pound to create 90 pounds of a coffee that can sell for $11.23 per pound. How many pounds of each kind of coffee should they mix?

Answer 1

13.5x +11.2(90-x)= 11.23(90)

solve for x=amount of $13.50

90-x= amount of $11.20

13.5x-11.2x = 11.23(90)- 11.2(90)

2.3x =.03(90)

x= 2.7/2.3=about 1.174 lb $13.50

90-x=about 88.826 lbs $11.20

227/3
