WILL GIVE BRAINLIST: How can you apply round numbers in real life? Justify your answer by providing a real life situation.

When you're at the grocery store. For example, you're shopping for paper plates, and the price says they are $4.90, you want to round that to $5 because of tax, and because you don't want to be that person telling the cashier that you don't have enough money.

hope this example is good and helps :)

because they could drop even lower..
