Question

The daily cost of hiring an electrician, y, to work x hours on a repair project can be modeled using a linear function. The electrician charges a fixed cost of $90 plus an additional cost of $60 per hour. The electrician works a maximum of 10 hours per day. For one day of work, what is the domain of the function for this situation?D: _ _ _

Answer 1

we have the following:

$c=90+60\cdot h$

the domain corresponds to input the input values, that is, the number of hours, therefore, it would be an open interval from 0 to 10 closed:

$(0,10\rbrack$
