At the pet store, there are 7 puppies and 6 kittens for sale. Two puppies and three kittens are sold. How many pets remain at the store? Give the rationale and then the answer.
Let's think step by step. There are 7 + 6 = 13 pets. They sell 2 + 3 = 5 pets. After the sales, there are 13 - 5 = 8 pets.. The answer is: 8.

James was 2/3s as tall as his uncle who is 72 inches. He gets a growth spurt that makes him gain 10 inches. How much taller is his uncle than James now? Give the rationale and then the answer.
Let's think step by step. He was 72 * 2 / 3 = 48 inches tall before. He is now 48 + 10 = 58 inches. So his uncle is 72 - 58 = 14 inches taller.. The answer is: 14.

For every 1 minute that Carlotta sings on stage during the final opera performance, she spends an additional 3 minutes practicing and 5 minutes throwing temper tantrums. If her final stage performance is 6 minutes long, what is the total combined amount of time, in minutes, that she spends practicing, throwing tantrums, and singing in the final stage performance? Give the rationale and then the answer.
Let's think step by step. For each 6 minutes she performs, Carlotta spends 6 * 3 minutes = 18 minutes practicing. For each 6 minutes she performs, Carlotta throws tantrums for 6 * 5 minutes = 30 minutes. Thus, in total, for each 6 minutes of performance time, she spends 18 minutes + 30 minutes + 6 minutes = 54 minutes on all three activities.. The answer is: 54.
