Copper and nickel electroless plating processes are under consideration for printed circuit boards. The copper process has fixed costs

of $$110,000$ per year with a variable cost of $$54$ per batch. The nickel process has a fixed cost of $$80,500$ per year and a variable cost

of $$90$ per batch. Determine the number of batches that must be produced each year in order for the processes to break even.

The number of batches that must be produced each year in order for the processes to break even is

batches.
