Elaine offers Fran part time cleaning work for $10.00 per hour. Fran says she wants $15.00 per hour. Elaine says: "I'll give you $12.00". Fran responds by saying: "Give me $15.00 and I'll bring my own cleaning products." Elaine says: "OK but what kind of products do you use?" "I use domestos, ajax, the usual range" replied Fran. "Oh, no" said Elaine "I can only have environmentally friendly products used in my home. $13.00 per hour and use my products. Take it or leave it." Fran looks doubtful. "Come on," says Elaine "If I don't hear from you by 5pm, I'll take it that you're OK with that and expect you tomorrow morning." Is there an agreement between Elaine and Fran?

The answer should be using IRAC (Issue, rule, application and conclusion) method and referred to the Australian Consumer Law. I need help on how to structure it and any key references that I should mention to answer it in detail. Also, if you can list the exact law excerpts that are used as a point of reference. Many thanks, your answers are kindly appreciated.
