Q: Eastern rattlesnakes have 6 segments in their tails, while Western rattlesnakes have 8 segments. What is the percentage difference in their tail size, expressed as a percentage of the Western rattlesnake's tail size?
A: First find the difference in size between the two kinds of snake tail: 8 segments - 6 segments = 2 segments. Then divide that amount by the size of the Western rattlesnake's tail and multiply by 100% to express the answer as a percentage: 2 segments / 8 segments * 100% = 25%. The answer is 25.
Question: Since the 40th president launched his reelection campaign today, he has raised $10,000 in campaign funds. His friends raised 40% of this amount and his family raised 30% of the remaining amount. The rest of the funds are from his own savings for the election. How much did he save for the presidency?
Answer: The total amount of money raised from friends contribution is 40 / 100 * $10000 = $4000. Minus his friend's contribution, the 40th president has raised $10000 - $4000 = $6000. The family raised 30 / 100 * $6000 = $1800. If the family raised $1800, the savings the 40th president had for the campaign is $6000 - $1800 = $4200. The answer is 4200.

First find how much the rail project will increase the house value by multiplying the initial value by 25%: $400,000 * .25 = $100,000. Then add that amount to the initial value to find the new value: $100,000 + $400,000 = $500,000. Then divide the maximum amount of property tax Jenny can afford to pay by the property tax rate to find the maximum value her house can have: $15,000 / .02 = $750,000. Now subtract the house's value after the rail project from the maximum value to find how much value the improvements can have: $750,000 - $500,000 = $250,000. The answer is 250000.
