Answer:
The total cost for 8 hours of work is $425.
The total cost for 10 hours of work is $525.
The total amount the plumber earns is made up of a fixed charge and a variable charge. A fixed charge is a charge that remains constant regardless of the number of hours the plumber works. The fixed charge is $25. The variable charge is the charge that increases per hours worked. The variable charge is $50 per hour.
Cost = fixed charge + variable charge
C = $25 + $50h
The total cost for 8 hours
$25 + $50(8)
$25 + $400
= $425.
The total cost for 10 hours
$25 + $50(10)
$25 + $500
$525.

The equation of the line thru <span> (14,5) and (19,15) is found as follows:
15-5 5
slope = m = ----------- = ------ = -1
19-14 5
Thus, the slope of any line perpendicular to this first line has the slope
m = -1/1 = -1.
Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>
2.125*10^4 x 10^4 / 1.25 x 10^3
= (2.125 / 1.25) x 10^(4 - 3)
= 1.7 x 10^1
= 17
