Each of the meals is prepared using a series of processes, one of which involves cooking the ingredients in a large oven. The availability of cooking time in the oven is limited and, because each of the meals requires cooking at a different oven temperature, it is not possible to cook more than one of the meals in the oven at the same time.

*The fixed conversion costs are general fixed costs that are not specific to any type of ready meal.
