a rabies clinic charges $5.00 for vaccination. each vaccine costs $0.48, a syringe and needle cost $0.09 and the labor for the veterinarian is $1.35. if 168 pets are vaccinated, what is the profit after all expenses are subtracted?
The profit is given by
168 (5 - .48 - .09 - 1.35 ) =
168 ( 3.08) =
$ 517.44
$${\mathtt{1.92}}{\mathtt{\,\times\,}}{\mathtt{168}}{\mathtt{\,-\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{168}} = -{\mathtt{517.44}}$$
