Q: Karen works at an animal shelter with 30 dogs, 28 cats, and 20 lizards. Every month, 50% of the dogs are adopted, 25% of the cats are adopted, and 20% of lizards are adopted. If the shelter takes in 13 new pets a month, how many pets are there after one month?
A: First find how many dogs get adopted each month by multiplying the number of dogs by their chance of getting adopted: 30 dogs * 50% = 15 dogs. Then do the same thing for the cats: 28 cats * 25% = 7 cats. And do the same thing for the lizards: 20 lizards * 20% = 4 lizards. Now add up the number of each kind of pet to find the initial total number of pets: 30 dogs + 28 cats + 20 lizards = 78 pets. Now subtract all the pets that get adopted in one month from the initial number of pets: 78 pets - 15 dogs - 7 cats - 4 lizards = 52 pets. Now add the extra 13 pets the shelter takes in that month to find the final number of pets: 52 pets + 13 pets = 65 pets. The answer is 65.
Question: Carter grew 9 plants with 3 seed packets. How many more seed packets does Carter need to have a total of 12 plants in his backyard?
Answer: If he grows 9 plants with 3 seed packets, he grows 9 / 3 = 3 plants with 1 seed packet. Since 1 seed packet grows 3 plants, he'll need 1 more to make the plants 12. The answer is 1.
[Question]Jessica is having a sweet tooth and bought 10 chocolate bars, 10 packs of gummy bears, and 20 bags of chocolate chips. Her total rang up to $150. If the cost of a pack of gummy bears is $2 and a bag of chocolate chips costs $5, how much does 1 chocolate bar cost?
[Answer]The gummy bears cost 10 * 2 = $20. The chocolate chips cost 5 * 20 = $100. The total cost for these two is 100 + 20 = $120. The chocolate bars in total cost 150 - 120 = $30. A single chocolate bar costs 30 / 10 = $3. The answer is 3.
Q: Jane bought 2 skirts for $13 each. She also bought 3 blouses for $6 each. She paid the cashier $100. How much change did she receive?
A: The 2 skirts cost $13 x 2 = $26. The 3 blouses cost $6 x 3 = $18. The total cost for 2 skirts and 3 blouses is $26 + $18 = $44. Jane received $100 - $44 = $56 change. The answer is 56.
Question: Nicky went to the DMV. He spent 20 minutes waiting to take a number, and quadruple that amount of time plus 14 minutes waiting for his number to be called. How long did he wait total?
Answer: First find how long Nicky spent waiting for his number to be called: 4 * 20 minutes + 14 minutes = 94 minutes. Then add the time he spent waiting to take a number: 94 + 20 = 114 minutes. The answer is 114.
Q: Over the past five years, on July 4th, the high temperature for Washington, DC has been: 90 degrees in 2020, 90 degrees in 2019, 90 degrees in 2018, 79 degrees in 2017 and 71 degrees in 2016. What is the average temperature for July 4th in Washington, DC over the past 5 years?
