Oriole's Candles will be producing a new line of dripless candles in the coming year and has the choice of producing the candles in a large factory with a small number of workers or a small factory with a large number of workers. Each candle will be sold for $$10.$ If the large factory is chosen, the cost per unit to produce each candle will be $$3\mathrm{.}00.$ The cost per unit will be $$7\mathrm{.}50$ in the small factory. The large factory would have fixed cash costs of $$2\mathrm{.}5$ million and a depreciation expense of $$300,000$ per year, while those expenses would be $$540,000$ and $$100,000,$ respectively in the small factory.

Calculate the number of candles for which the accounting operating profit at Oriole's Candles is the same regardless of the factory choice.

At unit sales the two factories would yield the same accounting operating profit.
