A:
Answer:24 pounds of 1.35 and 6 pounds of 1.15Step-by-step explanation:First you need to be able to write equations:x: pounds of 1.40 coffee in the mixy: pounds of 1.15 coffee in the mixHe wants to mix 30 pounds:x+y= 30Also the new price will be 1.35:1.40*x + 1.15*y = 1.35Replacing y = 30 - x1.40*x + 1.15(30-x) = 1.35Solving that you get:x = 24y = 6
