The current market price for Tatty is $75 and for Messy $60 and, at these prices, customers will buy as many units as are available.
The capacity of the two processes limits the amount of units of products that can be produced. Blasting can be carried out for 8 hours per day but smoothing can only operate for 6 hours per day.
