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.

At the time when Mac initially made his offer to Ashley, did she have the power of acceptance?

		Yes, because Mac manifest (expressed) a present intention to be legally bound in contract to Ashley under the terms that he described to her.
		No, because any reasonable person would know that no self-respecting man would have any intention of working on any day when Rebecca Black was going to be in town.
		Yes, but only if Ashley was induced to accept Macs offer by the prospect of having her car washed.
