Question

Abigail is working through her summer reading list. She must read a total of three books. Together, the three books have 530 pages. Abigail is four weeks into the summer, and, so far, her daily average of pages has resulted in a decrease in the total number of pages she must read by 133 pages. What is the division problem to represent the change in pages, on average, each day?

a) (530 - 133) / (4 * 7)
b) (530 + 133) / (4 * 7)
c) 530 / (4 * 7) - 133
d) (530 - 133) / 4

Answer 1

The correct choice is option a.), which represents the average number of pages Abigail has read per day: (530 - 133) divided by (4 weeks * 7 days per week).

Step-by-step explanation:

The student is trying to determine the average number of pages she has read per day. To calculate this, she needs to use the division problem that represents the reduction in the total number of pages across the number of days she has been reading. Since Abigail started with 530 pages and has read 133 pages, we subtract 133 from 530 to find how many pages are left. Then, we divide that number by the total number of days that have passed, which is 4 weeks times 7 days per week. The correct division problem for finding the average daily pages read is (530 - 133) / (4 * 7), which corresponds to option a.) from the choices given.
