Answer:

3 hours

Step-by-step explanation:

A plumber charges a diagnostic check of $65-this is also like a flat fee meaning, 0 hours=$65.

if you have a total of $320 in your wallet and the plumber charges $85 per hour, you simply do the following:

320-80=$240 remaining after the diagnostic check. To solve for how many hours he can work before you loose all your money:

$240-$85=3
