We have a question: Jim and his Cousin are out at a restaurant. They each order a cheeseburger and milkshake. They also split an order to cheese fries. A cheeseburger is $3. A milkshake is $5. Cheese fries are $8. They spend 80% of their combined money. If Jim brought $20 how much did his cousin bring?
And an answer: 10
So how you got the answer?
They spent $8 each on cheeseburgers and milkshakes because 3 + 5 = 8. They spent $16 on these items in total because 2 x 8 = 16. They spent $24 on their meal because 16 + 8 = 24. They had $30 to start because 24 / .8 = 30. His cousin had $10 because 30 - 20 = 10.

We have a question: Amanda had 7 candy bars. She gave 3 to her sister. The next day, Amanda won some prize money and bought another 30 candy bars. She gave her sister 4 times as many candy bars as she did the first time. How many candy bars did Amanda keep for herself altogether?
And an answer: 22
So how you got the answer?
Amanda has 7 - 3 = 4 candy bars. Amandy gives her sister 4 x 3 = 12 candy bars. She has 30 - 12 = 18 candy bars remaining. In total she keeps 18 + 4 = 22 candy bars.

He drinks 128 / 2 = 64 ounces of coffee every 4 days. That means he drinks 64 / 4 = 16 ounces of coffee a day. So he drinks 16 / 8 = 2 cups a day.
