Question

An electrician charges a set fee of $50 for every house call and then charges an additional hourly rate. One day, the electrician earned a total of $400 for a 5 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.

Answer 1

Answer:

$50+5t=C$

Step-by-step explanation:

Suppose the electrician spends t hours at the house working.

Amount charged for every house call by electrician = $50

The electrician earned a total of $400 for a 5 hour job.

Also, C denotes total cost of the electrician's services.

So, the equation for C in terms of t is given below.

$50+5t=C$

Here, $C=400$
