[Question]Ahmed and Emily are having a contest to see who can get the best grade in the class. There have been 9 assignments and Ahmed has a 91 in the class. Emily has a 92. The final assignment is worth the same amount as all the other assignments. Emily got a 90 on the final assignment. What is the minimum grade Ahmed needs to get to beat Emily if all grades are whole numbers?
[Answer]Ahmed has scored 819 total points in the class thus far because 9 x 91 = 819. Emily had scored 828 total points before the final assignments because 9 x 92 = 828. She scored 918 total points after the final assignment because 828 + 90 = 918. Ahmed needs to score a 99 to tie Emily for the semester because 918 - 819 = 99. Ahmed needs to score a 100 to beat Emily for the semester because 99 + 1 = 100. The answer is 100.

[Question]Ellis is going to take a road trip with her family. First, she needs to figure out how many bottles of water she should bring for everyone. There will be four people total: Ellis, her mother, her sister, and her aunt. They will be on the road to their destination for 8 hours and drive 8 hours to return home. Every hour each person will want to drink 1/2 a bottle of water. How many water bottles will Ellis' family need total?
[Answer]Ellis and her family of 4 will be traveling for 8 hours going and 8 hours coming home = 16 hours total. Each person needs 1 / 2 a bottle of water each hour, so 1 / 2 a bottle x 16 hours = 8 bottles. There are 4 people traveling so 8 total water bottles for each person x 4 people = 32 total water bottles. The answer is 32.

[Question]In a fundraiser car wash activity, the 5th graders raised $147 on Friday. On Saturday, they made $7 more than twice their Friday earnings. Their earnings on Sunday are $78 more than their earnings on Friday. How much did they earn in three days?
[Answer]Twice their Friday's earnings is $147 x 2 = $294. So, their Saturday earnings was $294 + $7 = $301. Their Sunday earnings was $147 + $78 = $225. Therefore, their total earnings in three days was $147 + $301 + $225 = $673. The answer is 673.

[Question]Beatrice is shopping for a new TV. First she looks at 8 TVs at one store in person. Then she looks at three times as many TVs at an online store. She looks at more TVs on an auction site online. If Beatrice looked at 42 TVs in all, how many did look at on the auction site?

Beatrice looked at 3 x 8 TVs at an online store = 24 TVs. She looked at 8 TVs in person + 24 TVs online = 32 TVs. Beatrice looked at 42 TVs in all - the 32 she looked at = 10 TVs she looked at on an auction site. The answer is 10.
