Ali a gardner is preparing to fertilize your lawn. the lawn is 30 yards by 25 yards. one bag of fertilizer will cover an area of 100 square yards. how many bags of fertilizer does ali need to buy?

So first we need to figure out the area of the lawn:

Area= l*w
A= 25*30 =750

This means that one bag of fertilizer will only cover about 1/7 of the entire thing so we will need 8 bags of fertilizer because
750/100 = 7.5 but since you can't have half a bag of fertilizer you round up to 8.
