Question 1

The Queen's Wardrobe,a dressmaking boutique,agrees to make Rhonda's wedding dress for $2,000.The dress is to be ready for her wedding on June 1^st.On May 14^th,Jane,the owner called Rhonda to tell her that the dress would not be ready on time unless Rhonda agreed to pay an extra $500 so that Jane could hire someone to help her finish the lace embroidery.Rhonda is very upset,and feeling that she has no other choice,agrees.When she picks up the dress,she tells Jane that she does not think that it is fair that she should have to pay more than they had agreed upon and refuses to do so.

A)Since Rhonda has received the benefit of Jane having paid the extra money to get the dress completed on time,she must pay the extra money.
B)By agreeing to pay and then refusing to do so,Rhonda has committed tort of deceit and a court would award Jane the $500.
C)Since Jane was obligated under the contract to make the dress for $2,000,there is no consideration for Rhonda's promise to pay more and it is therefore unenforceable.
D)Since Rhonda agreed to pay more,she has altered the terms of the contract and must therefore pay the extra $500.
E)Since the cost of hiring the extra worker to finish the embroidery was the consideration Jane gave for Rhonda for the money,she must pay it.

A)Since Software Design gave no consideration for Angela's classmate's promise to forgive the rest of the debt,Angela's classmate can successfully sue the company for the balance.

Question 6

Dimitri wrote to Pat offering to sell his neo-expressionist painting,"Red Sails in the Sunset," for $25,000.Pat replied that,since it would require that he redecorate,he could not really pay more than $18,000 for the painting.Dimitri replied that he was greatly hurt and deeply insulted by such an offer,especially from someone who was supposed to be a connoisseur of fine art,but that,since he was a little tight for cash,he would be willing to let it go to Pat for $13,000 for old times' sake.Pat immediately replied,saying that he accepted the painting at $13,000 and enquiring whether Dimitri wanted it in cash.Dimitri then realized that he had typed "$13,000" instead of "$23,000" in his second letter to Pat.

A)Since a reasonable person would have realized that Dimitri had made a mistake,given their prior correspondence,a court would not allow Pat to snap up the offer.
B)Since the courts do not consider the adequacy of consideration in determining whether or not a contract has been reached,Pat will be able to enforce the contract for $13,000.
C)Pat could not be expected to read Dimitri's mind and,since he accepted the offer in good faith,Dimitri cannot now back out of their contract.
D)It is not the function of the court to consider the motives of a party negotiating a contract in asking for what to others might seem to be inadequate consideration from the other party,so Pat will be able to enforce the contract.
E)It was up to Dimitri not to make mistakes like this and the court will not allow him to use his own carelessness to excuse him from meeting his obligations under the contract.

Question 25

X owed Y a debt in the amount of $1,000.The debt was payable on June 1^st.If Z,a friend of X,paid $900 to Y as payment in full of the debt owed by X,and Y accepted the sum,Y could not later demand the remaining $100 from X.

Question 55

Save-A-Lot Food Stores Limited regularly purchased large quantities of raisins for its bulk food section from a Canadian food wholesaler.The purchase of raisins was carried out with a separate purchase order and invoice each time although a full,written contract had been executed between the parties governing the relationship in its entirety.One of the terms of the contract specified that for individual orders in excess of 100 kg,a quantity discount of 15% would be applied to the purchase price.Since these were very favourable terms,Save-a-Lot regularly ordered quantities ranging between 500-700 kg of raisins to adequately supply all of its stores.After it had been purchasing raisins for over a year,Save-A-Lot received a note attached to its most recent invoice informing it that the contract was in error.The wholesaler's policy was that only purchases in excess of 1000 kg were entitled to the quantity discount of 15%.The invoice showed the full amount owing for the most recent purchase of 650 kg with no discount applied and also a cumulative amount equal to the 15% discount which had been granted to Save-A-Lot on all previous orders.Save-A-Lot refused to pay the extra amount
