Answer:
Part A.) 70 pages each day
Part B.) Nora has already read 84 Pages, She has 196 pages remaining. Nora should choose OPTION 1 because it will take her 4 NIGHTS to finish it instead of 7 NIGHTS with OPTION 2
Step-by-step explanation:
A.) You need to find 25% of 280. In order to do so, you can convert 25% into a decimal by moving its decimal two places to the left. 25.0% is then changed to 0.25. Next, simply multiply 0.25 by 280 to get 70 pages per night
B.) First you need to get 30% of 280
Like above, you simply multiply the decimal value of 30% to 280; the decimal value of 30.0% is 0.3(move decimal two places left) and 0.3 * 280 = 84 pages. Nora has already read 30% of the book, 84 pages.
Next you subtract 84 from 280 to get the remaining pages left. 280 - 84 = 196 pages left.
Finally, you compare the two options.
25% of 196 = 0.25 * 196 = 49 pages each night
196 / 49 = 4 nights until Nora completes the book
28 pages a night
196/ 28 = 7 nights until Nora completes the book
