Q. Anton must finish reading a 369page book in the next 7 days. Which of the following inequalities can be used to represent x, the average number of pages he must read each day to finish the book on or ahead of schedule?Choose 1 answer:(A) 7x≥369(B) x+7≥369(C) 7x≥369(D) 7x<369
Calculate average number of pages: To determine the average number of pages Anton must read each day, we need to divide the total number of pages by the number of days he has to read the book. The total number of pages is 369, and the number of days is 7. So, we calculate the average by dividing 369 by 7.
Adjust for whole number of pages: The calculation gives us 369/7=52.71. This means that if Anton reads 52.71 pages per day, he will finish the book in exactly 7 days. However, since he cannot read a fraction of a page, he needs to read at least 53 pages per day to finish on time.
Formulate inequality: Since Anton must read at least 53 pages per day to finish the book in 7 days, the inequality must reflect that the number of pages read per day (x) times the number of days (7) must be greater than or equal to the total number of pages (369). This is represented by the inequality 7x≥369.
Check answer choices: Now, we need to check the answer choices to see which one correctly represents the inequality we have found. Choice (A) is incorrect because it suggests dividing x by 7, which does not match our requirement. Choice (B) is incorrect because it suggests adding 7 to x, which does not represent the daily average needed. Choice (C) correctly represents the inequality 7x≥369. Choice (D) is incorrect because it suggests that reading 7x pages should be less than 369, which would not allow Anton to finish the book in time.
