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 be accurate as possible.
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: 310.
