Answer:
A.) Decrease in $11,000
Explanation:
The Old machine Written down value is $12,500 and residual value is $1,500
So loss on old machine is $12,500-$1,500=$11,000
However annual depreciation on new machine is $25,000/5=2,500 which will reduce income as depreciation is an expense.
The savings in annual variable manufacturing costs is $26,000-$23,500=$2,500.The increase in depreciation expense of $2,500 offsets the savings in manufacturing costs of $2,500.Therefore no impact on income for both events.
Only loss on old machine will have negative impact of $11,000 on income
