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.

Answers

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 )

(E - 5)/(15) = h

We solved for h , h = (E - 5)/(15)
since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:)
