Marcy spends 12 minutes petting her cat and 1/3 of that time combing it. How many minutes does she spend with her cat in total? Give the rationale and then the answer.
Let's think step by step. First find the time Marcy spends combing the cat: 12 minutes / 3 = 4 minutes. Then add that to the time spent petting the cat to find the total time she spends with it: 4 minutes + 12 minutes = 16 minutes.. The answer is: 16.

Lea bought one book for $16, three binders for $2 and six notebooks for $1. Calculate the total cost of her purchases. Give the rationale and then the answer.
Let's think step by step. The binders cost 3 binders * $2 / binder = $6. The notebooks cost 6 notebooks * $1 / notebook = $6. The amount of Lea's purchases is: $16 + $6 + $6 = $28.. The answer is: 28.

At a gym, the blue weights are 2 pounds each, and the green weights are 3 pounds each. Harry put 4 blue weights and 5 green weights onto a metal bar. The bar itself weighs 2 pounds. What is the total amount of weight, in pounds, of Harry's custom creation? Give the rationale and then the answer.
Let's think step by step. The blue weights weigh 4 * 2 = 8 pounds. The green weights weigh 5 * 3 = 15 pounds. The weights weigh 8 + 15 = 23 pounds. The total is then 23 + 2 = 25.. The answer is: 25.
