Question: Yasna has two books. One book is 180 pages long, and the other book is 100 pages long. If Yasna wants to finish both of the books in two weeks, how many pages will Yasna need to read every day, if she reads an equal number of pages each day?
Answer with step-by-step thinking: The total number of pages is 180 + 100 = 280 pages. The number of pages Yasna needs to read every day for two weeks is 280 / 14 = 20 pages.
So the answer is 20.


Question: Tina is working on her homework when she realizes she's having a hard time typing out her answers on her laptop because a lot of the keys are sticky. She is trying to get her homework done before dinner, though, so she needs to decide if she has time to clean her keyboard first. Tina knows her assignment will only take 10 minutes to complete. Dinner will be ready at 5:30 p.m. Tina decides to time how long it takes to remove and clean one key and will then multiply that time by how many keys she needs to fix. She counts 15 keys that are sticky and times it to take 3 minutes to clean one. After Tina has cleaned one key, there are 14 left to clean. How many minutes total will it take for Tina to both clean the remaining keys and finish her assignment?
Answer with step-by-step thinking: Tina has already cleaned one key so she has 14 left which take 3 minutes each to clean, 14 x 3 = 42 minutes to clean all the keyboard keys. Her assignment will take 10 minutes to complete, so she needs 42 minutes + 10 minutes = 52 minutes total before dinner.
So the answer is 52.
