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 \(h=\frac{E - 5}{15}\).
