ABC Company agrees to supply $5,000$ electrical switches to EngineCo on August $8,$ for a total cost of $$50,000.$ In June, ABC faxes EngineCo and states that it cannot meet the production date, because the switches are more complex than ABC realized and production time is greater. The company can deliver the goods on time only by demanding that its employees work overtime. It requests an extra $$15,000$ for overtime, and EngineCo reluctantly agrees in writing to pay it$.$ Later EngineCo refused to pay the extra $$15,000.$ ABC sues EngineCo. EngineCo wins. ABC agreed to do it for $$50,000.$ EngineCo wins. ABC should have agreed to some additional work to provide consideration for the change to the agreement ABC wins. EngineCo agreed to modify their agreement ABC wins. It did the work so it is automatically entitled to be paid the extra money.
