Jabari is power washing houses for a summer job. for every job he charges an initial fee plus $30 for each hour of work . his total fee for 4- hour job for instance is $170. jabari total fee f for a single job is a function of the number t of hours it takes him to complete the job. write the functions formula

he Charges $30 an hour and worked 4 hours:

$30 x 4 = $120 in hourly fees.

Now subtract that from the total fee:

$170 - $120 = $50

His initial fee is $50

The equation would be f= 30t + 50

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
