Carlos sold his business inventory to Avi for $10,000. Under their agreement, Avi was to pay Carlos $1,000 per month over a 10-month period, commencing on March 1st of that year. Before the first payment was due, Carlos became indebted to Avi for $5,000. Carlos then assigned the $10,000 debt agreement to Malcolm. Notice of this assignment was given to Avi. When he discovered that he was to make all payments under the agreement to Malcolm, he informed Malcolm that he would not make a payment until August. He would then make only the five remaining payments under the agreement and consider the debt fully satisfied.
