First step: the area of the lawn equals 900 m² minus the area of his house and driveway, which is 180 m².

AP · Answer

@Mochi, you with me?

Mochi · Answer

720?

AP · Answer

Correct. 
Now, considering that each bag Shady Seed covers 275 m², that means that Michael would need 3 bags to cover the 720 m² of lawn. Because 275 * 2 = 550 m², which wouldn't cover the entire lawn.

AP · Answer

So find the cost for 3 bags of Shady Seed...

Mochi · Answer

275 * 3 = 825
Is that what I'm supposed to do?

AP · Answer

Well, 3 bags of Shady Seed cover 825 m², but you're just looking for the c o s t of 3 bags
So $$$11.79\times3$$
