Answer:

Let's call x the number of hours spent on the job.

Cheap car shop charges a total (we'll call it T) equal to 77+31x.

Best Repair in Town charges 150.

The sistem is:

T=77+31x

T=150

Solving it you can find the number of hours x that would take Cheap Car Shop to do the job and have a pay equal to the one of Best Repair in town. Under x, Cheap car shop is more convenient, over x, Best Repair in town is more convenient.

Please help me I’m in finals a don’t want to fail
Misha Larkins [42]

Answer:

1, 2, 3

Step-by-step explanation:

X <= 20 means that x has to be less than OR equal to 20.

The first option is -100. That's less than 20, so this statement is true.

The second option is 10. That's also less than 20, so this statement is also true.

The third option is 20. This is equal to 20, so this is also true.

The fourth option is 21, which is greater than 20, so it's not true.

The fifth option is 45, which is greater than 20, so it's not true.

Sorry I answered so late, hope this helps even though you probably don't need it anymore.
