To determine the steps involved in solving each problem, let's break it down:
1. Michelle has $60. If her friend Kristin has $300, what percent of Kristin's money does Michelle have?
To find the percentage of Kristin's money Michelle has, you divide Michelle's money by Kristin's money and multiply by 100.
Steps:
- Divide Michelle's money ($60) by Kristin's money ($300): 60/300 = 0.2
- Multiply the result by 100 to convert it to a percentage: 0.2 * 100 = 20%
Therefore, Michelle has 20% of Kristin's money.
2. To pass a test, Kristin had to get 75% of the answers correct. If there were 84 questions on the test, how many questions would Kristin need to answer correctly to pass the test?
To find the number of questions Kristin needs to answer correctly to pass the test, you multiply the total number of questions by the required percentage.
Steps:
- Multiply the total number of questions (84) by the required percentage (75%): 84 * 75/100 = 63
Therefore, Kristin would need to answer 63 questions correctly to pass the test.
3. Thirty years ago, calculators sold for $200. Today they sell for $10. By what percent did they decrease in price?
To determine the percentage decrease in price, you calculate the difference between the initial and final prices, divide it by the initial price, and multiply by 100.
Steps:
- Calculate the price decrease: $200 - $10 = $190
- Divide the price decrease by the initial price: $190 / $200 = 0.95
- Multiply the result by 100 to convert it to a percentage: 0.95 * 100 = 95%
Therefore, calculators decreased in price by 95%.
4. Carla has 22% of her paycheck taken for taxes. If the amount taken for taxes is $136.40, what is the amount of Carla's paycheck before taxes were taken out?
To find the amount of Carla's paycheck before taxes were taken out, you divide the tax amount by the tax percentage.
Steps:
- Divide the tax amount ($136.40) by the tax percentage (22%): $136.40 / 0.22 = $620
Therefore, Carla's paycheck before taxes were taken out is $620.
