Question: 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?
Answer: 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.
[Question]While buying DVDs at the store, Maria received a 25% discount. If the discount she received is $40, how much did she pay in total?
[Answer]Since 100 percent represent the original price, and she received a 25% discount which is $40, the original price is 100 / 25 * 40 = 160. Maria paid $160 - $40 = $120 after receiving the twenty - five percent discount. The answer is 120.
