2. The total maintenance costs of Silver Company in the last four months are presented below:
Month Machine hours Maintenance cost
January 7, 200 P450, 000

Prime cost is the total of all direct expenses incurred to make a particular product. It is the total of Direct materials + Direct labour + Direct expenses. These are the expenses which can be directly attributable to a particular product or which can be directly identifiable from a product.
Direct materials | 300000 |
Direct labor | 400000 |
Prime cost | 700000 |
Conversion cost is the total expenses incurred to convert the materials into finished product and it includes direct labour and overhead expenses.
Direct labour | 400000 |
Factory overhead variable | 80000 |
Factory overhead fixed | 50000 |
Conversion cost | 530000 |
Total Manufacturing cost is the total of all direct and indirect cost incurred to make a product. It is the total of prime cost and all indirect overhead.
Direct materials | 300000 |
Direct labour | 400000 |
Prime cost | 700000 |
Add Factory overhead: | |
Variable | 80000 |
Fixed | 50000 |
Cost of manufacturing | 830000 |
2. Variable cost per machine hour
As various activity levels and associated costs are given, use High-Low method.
Highest Activity level | 7200 | 450000 |
Lowest Activity level | 6400 | 418000 |
Difference (Hi - Lo) | 800 | 32000 |
Variable cost per unit = 32000 / 800 = 40 per machine hour
To calculate the total fixed cost, apply the variable cost per unit in one of the two levels:
If applied in highest level:
Total cost = Variable cost + fixed cost
450000 = (7200 x 40) + FC
Fixed Cost = 450000 - 288000 = 162000
If applied in lowest level:
Total cost = Variable cost + fixed cost
418000 = (6400 x 40) + FC
Fixed Cost = 418000 - 256000 = 162000
Budgeted maintenance cost in May if the company is planning to use 7, 500 hours.
Total cost = Variable cost + Fixed cost
= ( 7500 x 40 ) + 162000
= 300000 + 162000
= 462000
Budgeted maintenance cost in May if the company is planning to use 8, 000 hours.
Total cost = Variable cost + Fixed cost
= ( 8000 x 40 ) + 162000
= 320000 + 162000
= 482000
