Clifton Clocks has offered to provide the timer units to Carla Vista at a price of $33 per unit. If Carla Vista accepts the offer, the current timer unit supervisory and clerical staff will be laid off.

a) Calculate the total relevant cost to make or buy the timer units.

Total relevant cost	$953784		$1345080

b) Assume that if Carla Vista Water accepts Cliftons offer, the company can use the freed-up manufacturing facilities to manufacture a new line of growing lights. The company estimates it can sell 83,890 of the new lights each year at a price of $10. Variable costs of the lights are expected to be $7 per unit. The timer unit supervisory and clerical staff would be transferred to this new product line. Calculate the total relevant cost to make the timer units and the net cost if they accept Clifton's offer.
