Question

Molly starts on page 63, reads 23 pages 1st day, 30 pages 2nd day, seven more each addl day; what was last page on 30th day?

Answer 1

Explanation:

difference is 7 so we put the number of days on brackets and look for the difference between 23 and 7 so that we can know what we're going to add to get 23

23-7 =16

7(1)+16=23

7(2)+16=30

Therefore were looking for day 30

7(30)+16=226
