A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. What will be the total cost of 8 hours of work?
Responses
h= 25C + 50; $250
C=50h + 25; $425
C=50h + 25; $250
h=25C + 50; $425
The correct equation in slope-intercept form is:
C = 50h + 25
To find the total cost of 8 hours of work, plug in h = 8:
C = 50(8) + 25
C = 400 + 25
C = $425
Therefore, the total cost of 8 hours of work will be $425.
The correct equation in slope-intercept form for the cost, C, after h hours of service is C=50h + 25.
To find the total cost of 8 hours of work, substitute h = 8 into the equation:
C = 50(8) + 25 = 400 + 25 = $425.
So the total cost of 8 hours of work will be $425.
