[Question]Brooke is milking cows and then selling the milk at the market for $3 a gallon. Whatever milk doesn't sell, she turns into butter. One gallon of milk equals 2 sticks of butter. She then sells the butter for $1.5 a stick. She has 12 cows. Each cow produces 4 gallons of milk. She has 6 customers, each of whom wants 6 gallons of milk. How much money does she earn if she sells all her milk and butter?
[Answer]A gallon of milk makes $3 worth of butter because 2 x 1.5 = 3. A gallon of milk sells for the same amount as milk or butter because 3 = 3. She gets 48 gallons of milk because 4 x 12 = 48. She earns $144 selling the milk because 48 x $3 = 144. The answer is 144.

[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]Ralph has $54.00 worth of products in his cart. At the register, he asks if he could have a 20% discount on an item with a small issue. This item is $20.00 to start. They agree. Ralph also has a 10% coupon on his purchase, which he uses after the 20% discount on the item with the small issue. How much will all of his items cost?
[Answer]They approved 20% off of the $20.00 item so .20 * 20 = $4.00. The item has a $4.00 discount which can be applied from his final total of $54.00 so 54 - 4 = $50.00. Now he can use his 10% coupon on the $50.00 total so .10 * 50 = $5.00. The total was $50.00 but his $5.00 discount now makes it 50 - 5 = $45.00. The answer is 45.
