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