Jill earns $15 per hour babysitting plus a transportation fee of $5 per job. write a formula for e, jill's earnings per babysitting job, in terms of h, the number of hours for a job. then solve your formula for h.

Jill earns $15 per hour babysitting plus a transportation fee of $5 per job. Write a formula for E, Jill's earnings per babysitting job, in terms of h, the number of hours for a job

E  is the Jill's earnings

h is the number of hours for a job

$15 is the constant rate per hour so we use linear equation

y= mx+b, Instead of x  and y we use h and E

E = mh + b

m is the slope (constant rate $15)

b is the transportation fee $5

So equation becomes E = 15h + 5

Now we solve for h

E = 15h + 5 (subract 5 on both sides)

E - 5 = 15h (divide by 15 )

We solved for h ,
