Suzanne wants to raise money for charity by running a 5-kilometer race. Her parents have pledged to donate $10 for her first kilometer and double the donation for every successive kilometer. If Suzanne finishes the race, how much money will her parents donate?
Let's think: For the 2nd kilometer, the donation will be $10 * 2 = $20. For the 3rd kilometer, the donation will be $20 * 2 = $40. For the 4th kilometer, the donation will be $40 * 2 = $80. For the final kilometer, the donation will be $80 * 2 = $160. For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $310.. The answer is: 310.

Randy has $200 in his piggy bank. He spends 2 dollars every time he goes to the store. He makes 4 trips to the store every month. How much money, in dollars, will be in his piggy bank after a year?
Let's think: Randy spends 2 * 4 = 8 dollars every month. Randy spends 8 * 12 = 96 dollars in a year. Randy will have 200 - 96 = 104 dollars in his piggy bank after a year.. The answer is: 104.

Michonne is inviting her friends to her birthday party. She invites 6 of her friends from school and 12 of her friends from her neighborhood. Each of her friends asks if they can bring two friends along as well. How many people are going to Michonne’s birthday party?
