The first thing we must keep in mind is the following unit conversion:
[tex]1 gigabytes = 1 * 10 ^ 9 bytes
[/tex]
We have then that for 35 gigabytes:
[tex]35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes
[/tex]
Part A:
For this case we make the following rule of three:
2000 bytes --------------> 1 page
35*10^9 bytes ----------> x
From here, we clear x:
[tex]x = (35 * 10 ^ 9) / (2000)
x = 17500000 pages[/tex]
Part B:
Then, the number of 500-page books is:
[tex]n = (17500000) / (500)
n = 35000
[/tex]
