Lighters cost $1.75 each at the gas station, or $5.00 per pack of twelve on Amazon. How much would Amanda save by buying 24 lighters online instead of at the gas station?
First find how many packs Amanda would have to buy on Amazon: 24 lighters / 12 lighters/pack = <<24/12=2>>2 packs
Then multiply that number by the cost per pack to find the total cost from Amazon: 2 packs * $5/pack = $<<2*5=10>>10
Then multiply the total number of lighters Amanda buys by the cost per lighter at the gas station: 24 lighters * $1.75/lighter = $<<24*1.75=42>>42
Then subtract the total Amazon cost from the total gas station cost to find the savings: $42 - $10 = $<<42-10=32>>32
