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?
Let's think: He planned on 2 sodas per guest and invited 15 guests so 2 * 15 = 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 = 5 packs of soda. The soda was on sale for $3.00 per 6 pack and he was buying 5 packs so 3 * 5 = $15.00 for soda.. The answer is: 15.

Matt can buy key chains in packs of 10 for $20 or in packs of 4 for $12. How much money can he save if he chooses to buy 20 key chains at a lower price?
Let's think: The cost of each key chain in packs of 10 for $20 is $20 / 10 = $2. The cost of each key chain in packs of 4 for $12 is $12 / 4 = $3. There is a price difference of $3 - $2 = $1 per key chain between the two choices. By buying 20 key chains at a lower price, Matt can save 20x$1 = $20.. The answer is: 20.

A farmer living in the countryside has a certain number of children. One day, they followed him to the farm, each one with a bag to collect harvested apples. At the end of the day, each bag was filled with 15 apples each. On their way back home, 2 of the children have eaten 4 apples each and another child sold 7 of his apples. If they had a total of 60 apples left by the time they got home, how many children does the farmer have?
Let's think: 2 children sold 4 apples each which gives 2 * 4 = 8 apples. Another child gave out an additional 7 apples making 8 + 7 = 15 apples removed from the total. There were 60 apples left after these, so the original total must have been 15 + 60 = 75 apples. Each child collected 15 apples so there are 75 / 15 = 5 children.. The answer is: 5.

James burned his hand in a freak accident. It takes him 4 weeks to heal enough to get a skin graft. After that it takes him 50% longer than that to heal from the skin graft. How long did he take to recover from everything?
Let's think:
The skin graft took 4 * .5 = 2 weeks longer to recover from than the previous. So that means it took 4 + 2 = 6 weeks to recover from it. That means he took 4 + 6 = 10 weeks to recover from everything.. The answer is: 10.
