Part A:
1)
The cost of purchasing 5000 devices (DD11) per year = $14 × 5000 = $70,000
After discontinuing the manufacture of devices:
The direct materials = 0
The direct labor = 0
The variable factory overhead costs = 20% × $30,000 = $6,000
The fixed factory overhead costs = $55,000 - $2,000 = $53,000

Manufacturing the devices ( DD11 ) Purchasing the devices ( DD11 ) from an outside supplier The incremental cost or benefit
Total manufacturing costs ( $190,000 ) 0 $190,000
Costs of purchasing the devices 0 ($70,000) ( $70,000 )
Fixed factory overhead costs ($6,000) ( $6,000 )
Variable factory overhead costs ($53,000) ( $53,000 )
Total ( $190,000 ) ( $129,000 ) $61,000 gain/benefit

*It is recommended that Jetta Electronics Ltd. had better purchase the devices (DD11) from the outside source. A differential cost/benefit analysis is made and states that there is a gain $61,000 after purchasing the devices (DD11) and not manufacturing them. As the total costs of buying the devices are less than manufacturing them. As the total costs of the direct materials …show more content…

After that, both manufacturing and services become more capital intensive because of technological changes which resulted in prompting ABC system. ABC sees costs being incurred as activities. So, these activities should be used as the basis for allocating indirect costs to services and products. For example, machine hours, quality inspections, setups and material moves. All of these are basis for allocating indirect costs. ABC detects the invaluable and costly activities so it helps managers to avoid these activities and replace them with efficient ones. Using ABC provides managers with detailed cost information which helps them reduce costs and set a competitive
