John has 10 members of his family on his father's side. His mother's side is 30% larger. How many people are there in total? Give the rationale and then the answer.
Let's think step by step. His mother's side is 10 * .3 = 3 people larger than his father's side. So his mother's side has 10 + 3 = 13 people. So the total number of people is 13 + 10 = 23.. The answer is: 23.

Chandler can eat a total of 23 apples and Lucy can eat a total of 19 apples per week. If the farmer only delivers 1 time per month, how many apples do they have to order for a month? Give the rationale and then the answer.

Let's think step by step. Johnny bought 15 packs, and every normal pack has 1 red pencil. He should have 15 * 1 = 15 red pencils. 3 of the packs have 2 extra red colored pencils, so there are 3 * 2 = 6 extra red pencils. In total, Johnny has 15 + 6 = 21 red colored pencils.. The answer is: 21.
