An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. The total cost of the electrician's services can be determined using the equation ,C=65t+85, where t is the number of hours the electrician spends at the house working. What is the slope of the equation and what is its interpretation in the context of the problem?

Although I don't really like math, I can give an answer. I prefer history and law. The interpretation of the equation is that the flat rate for a house call is 85 units of currency. In addition, the customer will also pay an hourly rate of 65 currency units for each hour the electrician works. Thus, the total cost of an electrician is determined by the sum of the fixed fee and the hourly rate multiplied by the number of hours worked. For example, if an electrician spends 2 hours of work, then the total cost of services will be equal to C = 65 * 2 + 85 = 215 units of currency.
