Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 15.


Question: It takes 20 minutes for John to go to the bathroom 8 times. How long would it take to go 6 times?
Answer with step-by-step thinking: He spends 20 / 8 = 2.5 minutes each time he goes in. So it would take 2.5 * 6 = 15 minutes to go 6 times.
So the answer is 15.


Question: Each bank teller has 10 rolls of coins. Each roll has 25 coins. How many coins do four bank tellers have in all?

So the answer is 1000.
