What is 54% of $789.56?
- A. $426.37
- B. $363.20
- C. $426.36
- D. $526.38
Correct Answer: C
Rationale: To find 54% of $789.56, you need to multiply $789.56 by 0.54 (which represents 54% as a decimal). $789.56 * 0.54 = $426.36. Therefore, the correct answer is $426.36. When calculating a percentage of a number, you convert the percentage to a decimal by dividing by 100 (54% = 54/100 = 0.54) and then multiply it by the number to find the result. In this case, converting 54% to a decimal gives 0.54, and then multiplying by $789.56 gives the answer of $426.36.
Multiply: (99)(0.56) =
- A. 54.44
- B. 56.44
- C. 55.44
- D. 57.44
Correct Answer: A
Rationale: To multiply decimals, first ignore the decimal points and multiply the numbers as whole numbers. Then, count the total number of decimal places in both factors (2 in this case) and place the decimal point in the product so that it has the same total number of decimal places. Therefore, (99)(0.56) = 5544. After placing the decimal point, the answer is 54.44. Therefore, the correct answer is A: 54.44.
How many meters are in 2 kilometers?
- A. 2000 meters
- B. 0.002 meters
- C. 20 meters
- D. 0.2 meters
Correct Answer: A
Rationale: To convert kilometers to meters, you need to multiply by 1000 because there are 1000 meters in 1 kilometer. Therefore, 2 kilometers is equal to 2 x 1000 = 2000 meters. The correct answer is 2000 meters. This conversion is a fundamental mathematical operation used across different fields, such as science, engineering, and day-to-day measurements, to accurately convert between larger and smaller units of length.
If a reader reads 5 pages a day in a book that has 1,025 pages, how many days will it take the reader to finish the book? (Enter a numeric value only.)
- A. 205
- B. 210
- C. 200
- D. 215
Correct Answer: A
Rationale: To determine the number of days needed to finish the book, divide the total number of pages in the book (1,025) by the number of pages read per day (5): 1,025 · 5 = 205. It will take 205 days for the reader to finish the book by reading 5 pages per day. Therefore, the correct answer is A) 205.
If Mr. Parker owns 150 shares of stock in Stark Industries and receives $180.00 per year in dividends, how much does Mr. Rogers receive for an annual dividend if he owns 400 shares of the same company?
- A. 480
- B. 500
- C. 450
- D. 72000
Correct Answer: A
Rationale: To determine how much Mr. Rogers receives annually in dividends for his 400 shares, you can set up a proportion based on the number of shares. The ratio of dividends to shares for Mr. Parker is $180/150 = $1.20 per share. By applying this ratio to Mr. Rogers with 400 shares, the calculation would be $1.20 x 400 = $480. Therefore, the correct answer is A, $480.
