Today is Tony's 10th birthday. His parents have decided to start giving him a monthly allowance, but they suggest a different plan.
Tony's mother wants to give him $0.01 each month this year, $0.10 each month next year, $1.00 each month the third year, and so on multiplying the monthly amount by 10 each year until Tony's 16th birthday.
Tony's father wants to give him $10.00 each month this year, $20.00 each month next year, $30.00 each month the third year and so on, adding $10.00 to his monthly allowance each year until his 16th birthday.
Which deal is better his mom or his dad and why is it the best one?
