Question

!!HELP: 20 POINTS!! 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=65+60t, 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?

Answer 1

C=65+60t —> Move variables to the left side and change its sign ( - )

-60 t = 65-c —> divide both sides of the equation by -60

t = -13/12 + 1/60 c —> Write the solution t in parametric form


Answer:
t = -13/12 + 1/60 c , c eR

Uhm I’m not really sure about my answer but i hope it helps!
Sorry if it’s wrong..
Stay safe!
