Mac made the following statement to Ashley on Monday: I hereby offer to wash your car for you this coming Saturday at noon for ten dollars. I promise not to revoke this offer until this Friday at 5pm. Three days later (on Thursday), Ashley approached Mac and said: Hey there, handsome, Id like to take you up on your offer to wash my car. Mac responds by saying: Sorry, Ashley, I already made plans to go to the Rebecca Black concert instead.

Was Macs offer to Ashley revocable prior to Friday at 5pm?

		No, because all offers are irrevocable until a reasonable amount of time has passed.
		No, because Mac specifically promised that the offer would remain open until Friday at 5pm.
		No, because Mac was gettin down on Friiiiiday.
		Yes, because even though Mac promised that he would not revoke the offer until Friday at 5pm, the offer was nonetheless revocable prior to that time, because this was not an option contract.
