[Question]A cougar is sleeping for 4 hours at night, and a zebra for 2 hours more. How much time do both animals sleep in one week?
[Answer]The zebra sleeps for 4 + 2 = 6 hours. During one week, the cougar sleeps 4 * 7 = 28 hours. And the zebra sleeps 6 * 7 = 42 hours. Both animals sleep for 28 + 42 = 70 hours during one week. The answer is 70.

[Question]Colin ran his first mile in 6 minutes. He ran his next two miles in 5 minutes each and finished his 4th mile in 4 minutes. What was the average time it took him to run a mile?
[Answer]His first mile was in 6 minutes, then 5 minutes, another 5 minutes and his final mile was 4 minutes so it took him 6 + 5 + 5 + 4 = 20 minutes. It took 20 minutes to run 4 miles so his average time was 20 / 4 = 5 minutes per mile. The answer is 5.

[Question]Fern buys one pair of high heels for $60 and five pairs of ballet slippers for 2/3rds of the price of the high heels. How much does she pay total?
[Answer]First find the cost of one pair of ballet slippers: $60 * 2 / 3 = $40. Then find the total cost of the ballet slippers: $40 / pair * 5 pairs = $200. Then add that amount to the cost of the high heels to find the total cost: $200 + $60 = $260. The answer is 260.

[Question]It is recommended that men should consume no more than 150 calories of added sugar per day. Mark took a soft drink in the afternoon that contained 2500 calories, 5% of which was from added sugar. Then he bought some bars of candy which had 25 calories of added sugar each. If he eventually exceeded the recommended intake of added sugar by 100%, how many bars of candy did he take?
[Answer]
He consumed 2500 calories, 5% of which is added sugar to give 2500 * (5 / 100) = 125 calories of added sugar. He exceeded the recommended intake of 150 calories by 100% for a total consumption of 150 + (150(100 / 100)) = $300. This means he took in 300 - 125 = 175 calories from candy alone. Each candy had 25 calories so 175 calories which means he consumed 175 / 25 = 7 bars?. The answer is 7.
