Question: Timothy has $50 to spend at a souvenir shop. He sees some t-shirts that cost $8 each, key chains that sell 3 pieces for $2, and bags that cost $10 each. Timothy buys 2 t-shirts and 2 bags. How many pieces of key chains can he buy with the amount of money he has left?
Answer with step-by-step thinking: The two t - shirts amount to $8 x 2 = $16. The two bags amount to $10 x 2 = $20. So Timothy spent $16 + $20 = $36 for the shirts and bags. He still has $50 - $36 = $14 left to spend for the key chains. With the money, he can buy $14 / $2 = 7 sets of key chains. Therefore, he can buy 7 x 3 = 21 pieces of key chains.
So the answer is 21.


Question: John wants to finish a show in 5 days. There are 20 episodes and they are each 30 minutes long. How many hours does he have to watch a day?
Answer with step-by-step thinking: He wants to watch 20 * 30 = 600 minutes. So he needs to watch 600 / 60 = 10 hours. That means he needs to watch 10 / 5 = 2 hours a day.
So the answer is 2.


Question: Gretchen's local ice cream shop offers 100 different flavors. She was able to try a 1/4 of the flavors 2 years ago and double that amount last year. How many more flavors will she need to try this year to have tried all 100 flavors?
Answer with step-by-step thinking:
The shop offers 100 flavors and she tried 1 / 4 of the flavors so she had 100 * .25 = 25 flavors 2 years ago. Last year she ate double the amount from the previous year so she had 25 * 2 = 50 flavors. 2 years ago she ate 25 flavors and last year she had 50 flavors so she has had 25 + 50 = 75 flavors. The shop offers 100 flavors and she has had 75 flavors so she still needs to try 100 - 75 = 25 flavors.
So the answer is 25.
