Current Attempt in Progress

Cullumber's Candles will be producing a new line of dripless candles in the coming years 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 $$10.$ If the large factory is chosen, the cost per unit to produce each candle will be $$2\mathrm{.}40.$ The cost per unit will be $$6\mathrm{.}80$ in the small factory. The large factory would have fixed cash costs of $$1\mathrm{.}6$ million and a depreciation expense of $$300,000$ per year, while those expenses would be $$480,000$ and $$100,000,$ respectively in the small factory.

Calculate the number of candles for which the accounting operating profit at Cullumber's Candles is the same regardless of the factory choice. $($Round answer to nearest whole units, e$.$g$.152.)$
