[Question]: Last week, a farmer shipped 10 boxes of pomelos which had 240 pomelos in all. This week, the farmer shipped 20 boxes. How many dozens of pomelos did the farmer ship in all?
[Answer]: There were 240 / 10 = 24 pomelos in a box. This means that each box has 24 / 12 = 2 dozens of pomelos since 1 dozen is equal to 12. The farmer shipped a total of 10 + 20 = 30 boxes. Thus, the farmer shipped a total of 30 x 2 = 60 dozens of pomelos.
So the answer is 60.

[Question]: Jerry was asked by her mom to do grocery shopping. He needs to buy 2 liters of mustard oil that costs $13 per liter, 3 pounds of gluten-free penne pasta that costs $4 per pound, and 1 pound of pasta sauce that costs $5. If Jerry can keep the rest of the $50 after grocery shopping, how much money will he have?
[Answer]: The cost of 2 liters of mustard oil is $13 x 2 = $26. The cost of 3 pounds of gluten - free penne pasta is $4 x 3 = $12. So, Jerry spent a total of $26 + $12 + $5 = $43 for grocery shopping. Thus, Jerry will have $50 - $43 = $7 for himself.
So the answer is 7.

[Question]: Jeff has a shelter where he currently takes care of 20 cats. On Monday he found 2 kittens in a box and took them to the shelter. On Tuesday he found 1 more cat with a leg injury. On Wednesday 3 people adopted 2 cats each. How many cats does Jeff currently have in his shelter?
[Answer]:
Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = 23 cats. 3 people took a total of 3 * 2 = 6 cats. After Wednesday, Jeff was left with 23 - 6 = 17 cats.
So the answer is 17.
