Answer:
There can be at most 28 lines that can be typed on a page
Explanation:
Given that:
• One line uses about 5/14 inch
,
• There are 0.5 inch margins at the top and bottom of a page
,
• The page is 11 inches long.
We want to know lines that can be typed on a page.
Let the number of lines that can be typed in a page be represented by x.
Then the addition of the number of lines that can be typed on a page, and the margins at the top and bottom, is at least 11.
This can be written as:
[tex]\frac{5}{14}x+2(0.5)\leq11[/tex]
Solving the inequality above, we have:
[tex]\begin{gathered} \frac{5}{14}x+1\leq11 \\ \\ \text{Substract 1 from both sides} \\ \frac{5}{14}x\leq10 \\ \\ \text{Multiply both sides by 14/5} \\ x\leq10\times\frac{14}{5} \\ \\ x\leq\frac{140}{5}=28 \end{gathered}[/tex]
There can be at most 28 lines that can be typed on a page.
