An electrican charges 40$ to come to your house. she also charges $55 for each hour that she works. the electrician charges you a total of $190.how many hours does the electrician work at your house? use h for the number of hours

190= 55h+40
Subtract 40
150=. 55h
Divide by 55
H= 2.7 hrs
More than 2 1/2 hrs

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
