225,000 = a + (6,500 x b)
125,000 = a + (2,500 x b)
–––––––– ––––––––––––––
100,000 = 0 + (4,000 x b)
therefore b = 100,000––––––– = £25
4,000
so, 225,000 = a + (6,500 x 25)
225,000 = a + 162,500
a = 225,000 – 162,500
a = 62,500
24 B Expected value of new building
= (0·8 x £2 million )+(0·2 x £1 million) – £1 million = £0·8 million
Expected value of the upgrade
= (0·7 x £2 million) + (0·3 x £1 million) – cost of upgrade
So,
New build = £0·8 million
Upgrade = £1·7 million – costs
Equating the two expressions:
£0·8 million = £1·7 million – costs, giving
Costs = £1·7 million – £0·8 million = £0·9 million = £900,000

The profit per unit for product A is £4 and for B is £10
3 (a) A service centre is a department that does not directly produce units but is required to support the other departments
Examples include maintenance departments, stores or a canteen
A production centre is a centre where units are actually made, examples being a machining department or a welding department
Although a service will have overheads allocated and apportioned to it, these will be reapportioned to the production centres
so that, at the end of a period, all overheads are included in the production centres only Once all the overheads are included
in the production centres they can be absorbed into production
(b) Activity based costing uses a number of different cost drivers to absorb different overheads, whereas traditional absorption costing only uses one, for example labour hours, machine hours or per unit
In activity based costing fixed overhead costs may include machine set-up costs These costs will not be incurred on a per unit basis but will be incurred each time the machine has to be set-up It would not, therefore, be sensible to allocate costs per unit since that is not how the cost is incurred It is, however, better to use the number of set-ups for this particular cost
to allocate costs to units
4 (a) Objective is to maximise profit:
Let a = the number of units of A to be produced
Let b = the number of units of B to be produced
Objective function: 9a + 23b
Constraints:
Non-negativity b ≥0
Restriction on A a ≥1,000
Materials 3a + 4b ≤30,000

Trang 8Optimal point is the intersect of the a = 1,000 line and the materials constraint line 3a + 4b = 30,000 (3 x 1,000) + 4b = 30,000
3,000 + 4b = 30,000 therefore 4b = 30,000 – 3,000 giving 4b = 27,000
so b = 27,000/4,000 therefore b= 6,750 units
The optimal production plan is to make 1,000 units of A and 6,750 units of B
