For this case, the first thing we must do is find the amount of money Alex will deposit in his bank account.

We have then:

[tex]125.75-42.50 = 83.25[/tex]

Then we look for the initial amount of money Alex has in his account. We have then:

[tex]x + 83.25> 194\\[/tex]

[tex]x> 194-83.25\\[/tex]

[tex]x> 110.75[/tex]

Then, we must graph this inequality to find the graph that represents the amount of money in Alex’s bank account prior to the deposit he made on Friday.
