Computing unit cost}

Argonaut Manufacturing Co. had 500 units, three-fifths completed, in process at the beginning of the month. During the month, 2,000 units were started in process and finished. There was no work in process at the end of the month. Unit cost of production for the month was \(\$ 1.20\). Costs for materials, labor, and factory overhead incurred in the current month totaled \(\$ 2,655\). Calculate the unit cost for the prior month. (Hint: You must first determine what the dollar balance in work in process must have been at the beginning of the month.)
