20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
<h3>

are the slopes of perpendicular lines</h3>
<em><u>Solution:</u></em>
We know that,
Product of slope of a line and slope of line perpendicular to it is always equal to -1
<em><u>Option 1</u></em>


Thus, these are not the slopes of perpendicular lines
<em><u>Option 2</u></em>

This option satisfies the slopes of perpendicular lines
<em><u>Option 3</u></em>

Thus, these are not the slopes of perpendicular lines
<em><u>Option 4</u></em>
2 and 2
Product = 2 x 2 = 4
Thus, these are not the slopes of perpendicular lines
You will know that it is greater than 10 because it goes into 621 more than 10 times
