Answer:
Multiple choices are:
18.5%
16.7%
34.6%
15.9%
The correct option is the last one,15.9%
Explanation:
The simple rate of return is the annual incremental net savings divided by the initial investment.
The annual incremental net savings is the annual savings recorded from the new process minus annual depreciation charge.
annual savings is $143,000
depreciation charge=cost of new equipment-salvage value of old equipment/useful life of the new equipment
depreciation charge=($414,000-$18,000)/6=$66,000
simple rate of return=$66,000/$414,000=15.9%
