Kara and Kevin are siblings, and have decided to discuss the idea of allowance with their parents since all of their friends get allowance for doing chores. Kara is only in elementary school, so she asks her mom if she can have $1 more dollar each day, starting with $3 on day 1. Kevin is in high school and wants to see if he can trick his little sister. Kevin asks for only $0.25 for the first day, but for his mom to double the amount of money he gets every day after that, so on day two he will get $0.50 and so on. Kara and Kevin’s mom agree to the terms. Kara laughs at Kevin because she thinks she will have way more money than him!
