36 Domco
Domco makes and sells a single product, Product P. It is currently producing
112,000 units per month, and is operating at 80% of full capacity. Total monthly
costs at the current level of capacity are $611,000. At 100% capacity, total monthly
costs would be $695,000. Fixed costs would be the same per month at all levels of
capacity between 85% and 100%.
At the normal selling price for Product P, the contribution/sales ratio is 60%.
A new customer has offered to buy 25,000 units of Product P each month, at 20%
below the normal selling price. Domco estimates that for every five units that it sells
to this customer, it will lose one unit of its current monthly sales to other customers.
Required
(a) Calculate the variable cost per unit of Product P and total fixed costs per
month.
(b) Calculate the current normal sales price per unit, and the contribution per unit
at this price.
(c) Calculate the effect on total profit each month of accepting the new customer’s
offer, and selling 25,000 units per month to this customer. Recommend
whether the customer’s offer should be accepted.

Note 1
Fixed overhead is absorbed on the basis of labour hours, based on a budget of
1,600 hours per quarter (three months).
During the next three months the number of direct labour hours is expected to
be limited to 1,345 hours. The same labour is used for all products.
The marketing director has identified the maximum demand for each of the
four products during the next three months as follows:
Liquid A 200 litres
Liquid B 150 litres
Liquid C 100 litres
Liquid D 120 litres
