Taylor is a buyer of file cabinets manufactured by Martin. Martin's contract with Taylor calls for delivery of fifty file cabinets at $40.00 per cabinet in five equal installments. After delivery of two installments (20 cabinets), Martin informs Taylor that because of inflation, Martin is losing money and will promise to deliver the remaining 30 cabinets only if Taylor will pay $50.00 per cabinet. Taylor agrees in writing to do so. Discuss fully whether Martin can legally collect the additional amount on delivery to Taylor of the next installment of 10 cabinets. Was there consideration for the amendment?
