320-65=255
255/85=3
you can afford 3 hours of work. 

Answer:

3 hours

Step-by-step explanation:

If the initial charge for the diagnostic check is $65 and you pay $85 for every hour of work then we can write the following expression with x being the number of hours worked:

[tex]65+85\cdot{x}[/tex]

and if you have $320 we can make the expression equal to 320:

[tex]65+85\cdot{x}=320[/tex]

We can solve x:

[tex]85\cdot{x}=320-65[/tex]

[tex]85\cdot{x}=255[/tex]

[tex]x=255/85=3[/tex]

You can afford 3 hours of work
