Question

Mr. Malone used 40 pounds of insecticide to cover 1760 ft.² of lawn and 60 pounds to cover an additional 2640 ft.² how many pounds of insecticide when Mr. Maloney to cover is a whole lawn of 4480 ft.²

Answer 1

Mr. Malone would need 102 pounds of insecticide to cover his entire 4480 ft.² lawn, calculated by finding the rate of insecticide used per square foot from two smaller sections of the lawn and applying it to the total area.

Step-by-step explanation:

Mr. Malone used insecticide to cover his lawn in two parts. For the first part, he used 40 pounds of insecticide for 1760 ft.². For the second part, he used 60 pounds for an additional 2640 ft.². The question requires us to calculate the total amount of insecticide needed to cover the whole lawn, which has an area of 4480 ft.².

To solve this problem, we can find the rate of insecticide used per square foot and then apply it to the total area:

• Total insecticide used: 40 lb + 60 lb = 100 lb
• Total area covered: 1760 ft.² + 2640 ft.² = 4400 ft.²
• Rate of insecticide per ft.²: 100 lb / 4400 ft.²
• Amount needed for 4480 ft.²: (100 lb / 4400 ft.²) * 4480 ft.²

After calculating, we find that Mr. Malone would need 102 pounds of insecticide to cover his entire lawn of 4480 ft.²

Answer 2

divide 4480 by 40

And for the 1760 ft multiply that twice
