The local firefighters are doing a “fill the boot” fundraiser. Their goal is to raise $6300. After the first 3 hours, they have raised $2100. For how many hours do they have to fundraise in total to reach their goal, assuming an equal amount raised in every hour?

How much do the firemen raise in each hour? ** The fireman raise 2100 / 3 = $<<2100/3=700>>700 per hour.
How many hours do they have to fundraise in total to reach their goal? ** They have to fundraise for 6300 / 700 = <<6300/700=9>>9 hours.
