Answer:

520<400+15x

15x>120

15x+400>520

Explanation:

Pay of Dan's car wash attendant job =$400 per week

The amount he earns per hour walking dogs = $15

Let the number of hours spent walking dogs in a week = x

Therefore, total earning for walking dogs =$15x

Since he wants to earn more than $520, we have that:

15x+400>520\text{  (Option F)}

We can rewrite this as:

520

If we collect like terms, we have:

\begin{gathered} 520-400

So the inequalities are:

0. 520<400+15x

,

1. 15x>120

,

2. 15x+400>520
