B. C=50h+25; $425
Explanation: The equation in slope-intercept form for the cost 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
C = 400 + 25
C = 425
Therefore, the total cost of 8 hours of work will be $425.
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
A.h=25c+50; $250
B.C=50h+25;$425
C.C=50h+25;250
D.h=25c+50;$425
