ii.Moses' sister Mona is concerned about his marks, and promised that she would give him $500.00 if he attended all his lectures and tutorials and achieved a Distinction in his Legal unit.Moses worked hard all term attending all classes and achieved a Distinction.When he asked Mona for the $500.00 she refused to pay.

iii.Sam, an engineering student at WSU, has a of pair light blue ASIC Gel Quantum 360's that Moses has shown an interest in as they are his size and have sold out in the stores.Sam says to Moses, "I will sell them to you if you give me $400.00 right now".Moses replies, "You've got a deal, but I will need to pay you in weekly instalments of $100.00".Sam walks off without saying anything further. The next day Moses finds out that Sam sold the shoes to his friend Luca for $350.00. He approaches Sam and says, "We had a deal, you owe me the shoes".

iv.Moses is in a hurry to get to his part-time employment on time. Lately, due to study commitments he has been late to work on several occasions and has been warned by his supervisor if this happens again he will lose his job.He gets into his car and notices that the car engine will not start as he left the car lights on and the battery went flat.Traci, a student at the same campus offered to drive Moses to work and Moses accepted.When Moses got to work on time, he was so grateful that he promised Traci he would buy her a lottery ticket.Moses did not give Traci the lottery ticket and when Traci claimed he had to, he told Traci that he is not obliged to give it to her.

Using IRAC, advise Moses whether a contract has been formed in each of the situations. In doing so, discuss fully all relevant legal principles that arise in the circumstances. Your answer must be supported with relevant legislation and case law authorities.
