Studying for her test, Mitchell had read ten chapters of a book before 4 o'clock. When it clocked 4, Mitchell had read 20 pages of the 11th chapter of the book she was studying from. After 4 o'clock, she didn't read the remaining pages of chapter eleven but proceeded and read 2 more chapters of the book. If each chapter in the book had 40 pages, calculate the total number of pages that Mitchell had read altogether? Give the rationale and then the answer.
Let's think step by step. Since each chapter of the book has 40 pages, Mitchell had read 10 * 40 = 400 pages from the first ten chapters. After reading 20 pages of the eleventh chapter, the total number of pages that Mitchell had read is 400 + 20 = 420. The next two chapters that she read had 2 * 40 = 80 pages. In total, Mitchell read 420 + 80 = 500 pages of the book that day.. The answer is: 500.

There are 78 pieces of fruit in a crate. One-third of the box contains kiwi. The rest are strawberries. How many strawberries are there? Give the rationale and then the answer.
Let's think step by step. One - third of the fruit: 78 / 3 = 26 kiwis. The rest are strawberries: 78 - 26 = 52. There are 52 strawberries in the crate.. The answer is: 52.

Val has three times as many dimes as nickels. If she accidentally finds twice as many nickels as she has in her older brother's treasure box, and takes them for herself, what would be the value of money she has, in dollars, if she had 20 nickels before finding the new ones from her brother's treasure box? Give the rationale and then the answer.
Let's think step by step. If Val currently has 20 nickels and finds twice as many nickels as she has in her older brother's treasure box, she will have 2 * 20 = 40 more nickels. The total number of nickels she'll have is 40 + 20 = 60. Since nickel is worth $0.05, the value of the nickels Val is having is 60 * 0.05 = $3. Val had three times as many dimes as nickels before she found the 40 new nickels, a total of 3 * 20 = 60 dimes. Since a dime has a value of $0.10, the value of the dimes that Val has is 60 * $0.10 = $6. Together, the value of the dimes and nickels Val has is worth $6 + $3 = $9.. The answer is: 9.
