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
