Question

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.

Answer 1

Jill earns $15 an hour but looses $5 per job if Jill has a two hour long job she would earn $25

Answer 2

Answer:

The formula for Jill's earnings per babysitting job is $E = 15h + 5$ and the formula in terms of h is $h=\frac{E - 5}{15}$.

Step-by-step explanation:

Consider the provided information.

Jill earns $15 per hour babysitting plus a transportation fee of $5 per job.

Let E represents the Jill's earnings and h is the number of hours for a job.

It is given that $15 is the constant rate for each hr.

So for h hours she will earn: $15h

The transportation fee is $5. So her total earning can be expressed by the expression.

$E = 15h + 5$

Now solve for h.

$E = 15h + 5$

Subtract 5 on both sides.

$E-5= 15h$

Divide both side by 15.

$\frac{E - 5}{15} = h$

$h=\frac{E - 5}{15}$

The formula for Jill's earnings per babysitting job is $E = 15h + 5$ and the formula in terms of h is $h=\frac{E - 5}{15}$.
