Answer the following question.
It takes John 13 seconds to run 100 meters. He only goes 4 meters in the first second. He then maintains the same speed for the rest of the race. James is 2 m/s faster at the top speed and he can run the first 10 meters in 2 seconds. How long does it take James to run 100 meters?
Step-by-step reasoning process: John runs 100 - 4 = 96 meters once he reaches his max speed. He runs it in 13 - 1 = 12 seconds. So he runs at a speed of 96 / 12 = 8 m / s. So that means James's top speed is 8 + 2 = 10 m / s. He has to run 100 - 10 = 90 meters at his top speed. So he runs that at 90 / 10 = 9 seconds. So he takes 9 + 2 = 11 seconds to run 100 meters.
The answer is 11.

Answer the following question.
June is running for class president. She needs just over 50% of the vote to win. There are 200 students in the school. 60% of students are boys and the rest are girls. If she receives 67.5% of male vote, what is the smallest percentage of the female she must receive to win the election?
Step-by-step reasoning process: 50% of the vote is 100 votes because 200 x .5 = 100. Just over 50% is 101 votes because 100 + 1 = 101. 120 students are boys because 200 x .6 = 120. 80 students are girls because 200 - 120 = 80. She gets 81 votes from boys because 120 x .675 = 81. She needs 20 votes from girls because 101 - 81 = 20. She needs a proportion of .25 of girl's votes to win because 20 / 80 = .25. The percentage she needs is 25 because 100 x .25 = 25.
The answer is 25.

Answer the following question.
Darryl sells melons on the side of the road. He sells cantaloupes for $2 each and honeydews for $3. He started the day with 30 cantaloupes and 27 honeydews. He accidentally dropped a couple of cantaloupes and three of the honeydews turned out to be rotten. At the end of the day he had 8 cantaloupes and 9 honeydews left. How much money did he make?
Step-by-step reasoning process: He dropped two cantaloupes and had 8 left over at the end of the day, so he sold 30 - 2 - 8 = 20 cantaloupes. Three honeydews were rotten, and he had 9 left at the end of the day, so he sold 27 - 3 - 9 = 15 honeydews. He sold 20 cantaloupes * $2 / cantaloupe = $40 in cantaloupes. He also sold 15 honeydews * $3 / honeydew = $45 in honeydews. Altogether he made $40 + $45 = $85.
The answer is 85.

Answer the following question.
Kenneth spent 10% of this earnings this week on a new joystick. If he is left with $405, how much were his earnings?
Step-by-step reasoning process: Since Kenneth spent 10%, then he is left with 100% - 10% = 90% of his earnings. Since 90% of his earnings is worth $405, then 1% of his earnings is $405 / 90 = $4.50. Hence, Kenneth's earnings is $4.50 x 100 = $450.
The answer is 450.
