It takes 50 oz of grass seed to seed 3000 ft2 of lawn. At this​ rate, how much would be needed for 7200 ft2 of​ lawn?
saw5 [17]

Answer:

120 ounces

Step-by-step explanation:

First find how many ft2 of lawn 1 once can seed.

To do this we simply divide 3000 by 50 ( because 50 ounces of grass seed can seed 3000 ft2 of lawn )

3000 / 50 = 60

So 1 ounce can seed 60ft2 of lawn

To find how many ounces would be needed to seed 7200 ft2 of lawn we would divide 7200 by the amount of lawn 1 once can seed ( which is 60ft2 )

7200/60 = 120

So 120 ounces of grass seed would be needed to seed 7200 ft2 of lawn
