Answer the following question.
Venus is at the deli to get subs for a party. She needs 81 inches of sub. The shop sells 5 and 8 inch subs. If she buys two 8 inch subs, how many 5 inch subs does she need to buy?
Step-by-step reasoning process: The two 8 inch subs total 16 inches because 2 x 8 = 16. She still needs 65 inches of sub because 81 - 16 = 65. She needs to buy 13 five inch subs because 65 / 5 = 13.
The answer is 13.

Answer the following question.
Jimmy wants to play in the inflatable swimming pool in his backyard. The swimming pool is empty and the garage is locked, so he cannot use the hose to fill the pool. He finds a 2 gallon bucket and calculates that it takes 20 seconds to fill the bucket from the tap and carry it to the pool where he pours in the water. If the pool holds 84 gallons of water, how many minutes will it take Jimmy to fill the pool?
Step-by-step reasoning process: It will take 84 / 2 = 42 trips to fill the pool with water. This will take Jimmy 42 trips * 20 seconds per trip = 840 seconds. This means that Jimmy will spend 840 seconds * 1 minute / 60 seconds = 14 minutes filling the pool.
The answer is 14.

Answer the following question.
The total average age of three friends is 40. Jared is ten years older than Hakimi, and Molly's age is 30. How old is Hakimi?
Step-by-step reasoning process: The total age for the three friends is 40 * 3 = 120. If Molly's age is 30, then Jared and Hakimi have a total age of 120 - 30 = 90. Let's say the age of Hakimi is x. Since Jared is 10 years older than Hakimi, Jared is x + 10 years old. Jared and Hakimi's total age is x + (x + 10) = 90. This translates to 2x = 90 - 10. 2x = 80. Hakimi's age is x = 80 / 2. This gives us x = 40, which is Hamkimi's age.
The answer is 40.
