Q: 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?

There are 4 people traveling so 8 total water bottles for each person x 4 people = 32 total water bottles. The answer is 32.
