The total pages in the book are 510.
Step-by-step explanation:
Lets say, the total pages are x
Mo read the book with following proportion.
Monday: 2/5.x
Pages left: 1.x - 2/5.x = 3/5.x
Tuesday: 1/2.x of 3/5.x = (1/2.x) . (3/5.x) = 3/10.x
Pages left: 3/5.x - 3/10.x = 3/10.x
Wednesday: 5/9.x of 3/10.x = (5/9.x) . (3/10.x) = 1/6.x
Thursday : ?
Lets say the total proportion is 1. The proportion of book read on Thursday can be calculated as:
1.x - 2/5.x - 3/10.x - 1/6.x = 2/15.x
Also given, Mo read 68 more pages on Tuesday than Wednesday.
Therefore,
3/10.x - 1/6.x = 68
2/15x = 68
x = 510
Therefore, the total pages in the book are 510.

Step-by-step explanation:
Can i have brainliest?
The question is incomplete as it is missing the length of the book spine and length of the staple.
Assume the question goes thus :
Elena is binding a small booklet with a spine that is 15 inches long. She uses staples that are 0.5 -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
Answer:
30 staples
Step-by-step explanation:
Given that:
Length of book spine = 15 inches
LENGTH of staple = 0.5 inch
Since it is assumed that staples are applied end-to-end on the book without gaps ; the number of staples which will be used is ;
Length of book spine / length of staple
= 15 inches / 0.5 inch
= 30 staples
560 divided by 4=140 140 divided by 7 equals 20
