Answer 2

Answer:

5 hours

Step-by-step explanation:

Erin needs $100 to pay the bill.

She has $25 in the bank.

First let's find how much money she needs more

$100-25=75$

She needs $75

They said that,

she earns $15 per hour from her job.

Let the unknown hours be x.

Now let's find the hours she have to work to earn $75

 1h = $15

 x  =  $75

Use cross multiplication

$75*1=15x\\\frac{75}{15} =\frac{15x}{15} \\5 h=x$

She needs to work for 5 hours in order to have the $100

Hope this helps you.
