Answer this question:There are 15 cats in a shelter. One-third were adopted, and were replaced with twice the amount that were adopted. Later on, twice as many dogs showed up as there are cats. How many total animals are there in the shelter?
15 / 3 = 5 cats were adopted out of 15. There were 15 - 5 = 10 cats left. 5 * 2 = 10 more cats were added. This makes 10 + 10 = 20 cats in the shelter. 20 * 2 = 40 dogs came into the shelter. There are now 20 + 40 = 60 animals in the shelter.
The answer is 60.

Answer this question:The sum of the three numbers is 500. If the first number is 200, and the value of the second number is twice the value of the third number, find the value of the third number.
Let's say the third number is x. The sum of the second and third number is 500 - 200 = 300. Since the third number is x, the sum of the values of the second and third number is x + 2x = 300. This is 3x = 300. The value of the third number is x = 300 / 3. x = 100.
The answer is 100.

Answer this question:Janet, a third grade teacher, is picking up the sack lunch order from a local deli for the field trip she is taking her class on. There are 35 children in her class, 5 volunteer chaperones, and herself. She she also ordered three additional sack lunches, just in case there was a problem. Each sack lunch costs $7. How much do all the lunches cost in total?
Janet needs 35 lunches for the kids + 5 for the chaperones + 1 for herself + 3 extras = 44 lunches. Each lunch is $7, so lunch for the field trip costs $7 per lunch * 44 lunches = $308 total.
The answer is 308.

Answer this question:A dragon hoards jewels and gold in its cave. A jealous king snuck in and stole three prize jewels. The dragon burned him to a crisp and stole back its jewels, along with twice as many of the king's crown jewels from his crown that melted in the dragon's fire. The new jewels were a third of the number of jewels the dragon had owned before. How many jewels did the dragon own in the end?
The dragon stole 2 * 3 = 6 of the king's crown jewels. The dragon owned 6 * 3 = 18 jewels before the theft. Thus, the dragon owned 18 + 6 = 24 jewels in the end.
The answer is 24.
