Question: Karen wanted to go out to get some fast food. She pulls up to the drive-through and orders a 5-dollar burger. Her son then yelled out that he wanted a 4-dollar sandwich, so it was added to the order. Karen then decided to order some drinks and opted for two 4-dollar smoothies. What is the total cost of Karen's fast-food order?
Answer with step-by-step thinking: Karen and her son order 5 + 4 = 9 dollars worth of food. Karen decides to buy 4 + 4 = 8 dollars worth of smoothies. The total for this order is 9 + 8 = 17 dollars.
So the answer is 17.


Question: Betty has a tray of cookies and a tray of brownies. She has a real sweet tooth and eats 3 cookies a day and 1 brownie a day. If she starts with 60 cookies and 10 brownies, how many more cookies than brownies does she have after a week of eating like this?
Answer with step-by-step thinking: First we find how many cookies Betty will eat in a week by multiplying her daily amount by 7, meaning 7 * 3 = 21 cookies eaten in a week. We repeat this for the brownies, finding she eats 7 * 1 = 7 brownies in a week. We subtract the 21 cookies from the original amount of 60, finding 60 - 21 = 39 cookies remaining. We repeat this step for the brownies, finding 10 - 7 = 3 brownies remaining. In the end, therefore, Betty has 39 - 3 = 36 more cookies than brownies.
So the answer is 36.


Question: An animal shelter recently took in twelve cats. The shelter already had half that number of cats. Two days later, three had been adopted. The next day, one of the cats had five kittens, and one person arrived to pick up one of the cats that was their missing pet. How many cats does the shelter have now?
Answer with step-by-step thinking:
The shelter started with 12 / 2 = 6 cats. The cats they took in increased the number to 12 + 6 = 18 cats. Three cats were adopted, so they had 18 - 3 = 15 cats. One cat had 5 kittens, which increased the number of cats to 15 + 5 = 20 cats. The pet owner came to get his missing cat, so they now have 20 - 1 = 19 cats.
So the answer is 19.
