If the electrician spent x hours on a particular job then the total charge C in dollars would be C = 65x + 25. This is a mathematical formula for the cost C.. This formula can be used to calculate the cost of using this electrician, by replacing x (substituting into x) the number of hours spent on a job.. For example if the electrician spent 1.5 hours on the job, then x = 1.5.

Now you probably know that an accessible route has a maximum slope of 5%, or it becomes a ramp and needs handrails. So 401' - 6 1/4" converts to 401.52. Then subtract 400.14 to find the grade change of 1.38'. To find the slope, divide the grade change of 1.38' by the distance of 30' to get a slope of .046 or 4.6%, which is less than the maximum ...
