What is the total number of digits required in numbering the pages of a book, which has 1,724 pages?

5,789 digits

Step-by-step explanation:

1 digit numbering from page 1-9

That is 9 pages×1 digit=9 digits

2 digit numbering from page 10 to 99

That is 90 pages × 2 digits=180 digits

3 digit numbering from page 100 to 999

That is 900 pages× 3 digits=2,700 digits

4 digits numbering from page 1000 to 1,724

That is 725 pages × 4 digits

=2,900 digits

Total digits=9 digits+ 180 digits+2,700 digits+2,900 digits

=5,789 digits

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
