Question

Would you rather read 12 pages every night in a chapter book with 144 pages or read 50 pages 3 times a week in a chapter book with 132 pages? Choose an option you would rather have and provide a mathematical justification as to why you made that choice.​

Answer 1

Read 12 pages every night in a chapter book with 144 pages.

Thus the first option is the best because you will use fewer number of days to complete the reading.

Explanation:

For the first option;

Read 12 pages every night in a chapter book with 144 pages, the number of days taken to complete the book will be;

144/12= 12 days

For the second option

50 pages = 3 times

132 pages = ? ------perform cross product

(132*3)/ 50 =7.92 ≈ 8 times

3 times = 1 week

8 times = ?

(8*1)/3 = 2.64 weeks

1 week =7 days

2.64 weeks=?

2.64*7 = 18.5 days

Thus the first option is the best because you will use fewer number of days to complete the reading.
