Li wants to buy as many bags of mulch as possible with his $305, and he would like them to be delivered to his house. The cost is $7.50 per bag and there is a $35.75 delivery charge. The mulch is only sold in full bags. How many bags can Li buy?

From Li’s initial amount of $305, a flat $35.75 delivery charge is deducted:
$305 − $35.75 = $269.25.
We can then divide this amount by the cost per bag to find the total number of bags that Li can buy:
$269.25 ÷ $7.50 = 35.9 bags. However, the question states that the mulch can only be sold in full bags, so we must round our answer down to ensure that Li does not exceed his budget.
