Question

What should Jorge do?
He should order online and pay the cheaper cost for
the sander
He should try to fix the sander he already has.
He should buy the sander in the store and pay more.
He should turn down the job.

Answer 1

He should buy the sander in store, this way it will be available for when he needs it.

Answer 2

He should buy the sander in the store and pay more.

By him paying $10 extra dollars, he decreases the risk of not being able to do the job at all. If he buys online, it may be shipped after the deadline (3 days), then he would not be able to gain the money back.

Hope this helps! :)
