On March 1, Dennis Storme telephones Mariah Wilson and leaves her this voicemail message:
(1)March 1, Dennis (voicemail message): Hello, I'm Dennis Storme. You come highly recommended as a math tutor, and I'd like you to tutor my daughter Susan in trigonometry. Would you get back to me so that we can discuss the possibilities?
(2)March 2, Mariah (voicemail message): Hello, Mr. Storme, this is Mariah Wilson. I would be happy to tutor Susan. I have only one opening at present—Saturday mornings from 10:30 A.M. to noon. My fee is $90 for the 90 minutes. I am prepared to commit to the next ten Saturdays. After that, we can consider whether Susan needs any additional tutoring.
(3)March 3, Dennis (fax): Thank you for your return call. I cannot work with the hours you mention. Would you be able to tutor on Saturday evenings?
(4)March 4, Mariah (voicemail message): No, Mr. Storme, I'm sorry that I cannot tutor Susan on Saturday evenings. Exactly as stated in my last message, I am available for the next ten Saturdays from 10:30 A.M. to noon and would be pleased to tutor Susan on those days at those hours.
(5)March 5, Dennis (fax): Very well—we're agreed. Saturday mornings from 10:30 A.M. to noon; I'll find some way to see that we can do it.
Legally, is Mariah free not to tutor Susan?
A.Yes, because Dennis's March 5 message was too indefinite to create a contract
B.Yes, because on March 3, Dennis lost his power to accept Mariah's March 2 offer
C.No, because on March 3, Dennis plainly continued in his willingness to purchase Mariah's services
D.No, because on March 5, Dennis effectively assented to the terms that Mariah had set forth on March 4
