Question: A chihuahua, pitbull, and great dane weigh a combined weight of 439 pounds. The pitbull weighs 3 times as much as the chihuahua. The great dane weighs 10 more pounds than triple the pitbull. How much does the great dane weigh?
Answer: Let x represent the weight of the chihuahua. Pitbull:3x. Great dane:10 + 3(3x) = 10 + 9x. Total:x + 3x + 10 + 9x = 439. 13x + 10 = 439. 13x = 429. x = 33 pounds. Great dane:10 + 9(33) = 307 pounds. The answer is 307.
[Question]In his phone gallery, Malachi has the number of selfies he took last year and this year in the ratio of 10:17. If he has 2430 photos in his gallery, how many more photos did he take this year than last year?
[Answer]The total ratio representing the number of photos in the Malachi gallery is 10 + 17 = 27. The difference in the ratios representing the number of photos Malachi took this year and last year is 17 - 10 = 7. This year, Malachi took 7 / 27 * 2430 = 630 more photos than he took last year. The answer is 630.
Q: Marianne was 20 years old when Bella was 8 years old. How old will Marianne be when Bella turns 18?
A: Marianne is 20 - 8 = 12 years older than Bella. Bella will turn 18 in 18 - 8 = 10 years. So, Marianne will be 20 + 10 = 30 years old then. The answer is 30.
Question: John has to pay taxes. He earned $100,000 for the year. He has $30,000 in deductions. The first $20,000 of taxable income is taxed at 10%. The rest is taxed at 20%. How much does he pay in taxes?
Answer: His taxable income is 100,000 - 30,000 = $70,000. So he pays 20,000 * .1 = $2000 tax at the lower rate. He has to pay 70,000 - 20,000 = $50,000 at the higher rate. The taxes for that is 50,000 * .2 = $10,000. So his total tax bill is 10,000 + 2,000 = $12,000. The answer is 12000.
[Question]Jamie is in a walking group with 4 other ladies. The ladies all walk 3 miles together. On top of that, Jamie walks an additional 2 miles per day for 6 days while her friend Sue walks half that amount in 6 days. If they walk this same route 6 days a week, how many miles do the ladies walk in total?
[Answer]There are 5 ladies total in the group. They all walk 3 miles a day for 6 days so 3 * 6 = 18 miles. Jamie walks an additional 2 miles per day for 6 days so 2 * 6 = 12 miles. Sue walks half the distance of Jamie so 12 / 2 = 6 miles. Together, the ladies walk 18 + 12 + 6 = 36 miles. The answer is 36.
