Fred was having a party and was responsible for buying canned soda.  He figured every guest would drink 2 sodas and he was inviting 15 people to the party.  The local store had a deal on sodas that week.  Every 6 pack of canned sodas was on sale for $3.00.  How much would it cost Fred to buy enough sodas for every guest to have 2 cans?
He planned on 2 sodas per guest and invited 15 guests so 2*15 =<<2*15=30>>30 cans of soda
Each pack of soda had 6 cans. He needed to buy 30 cans of soda for his guest so 30/6 = <<30/6=5>>5 packs of soda
The soda was on sale for $3.00 per 6 pack and he was buying 5 packs so 3*5 = $<<3*5=15.00>>15.00 for soda
