Answer:
The effect is an increase in net earnings of $20,000.
Step-by-step explanation:
As in the above, the effect on Lakeside's earning is calculated on cost/benefit basis.
Costs are incurred annually due to getting the office space through depreciation deduction while benefit is for annual lease rentals.
Yearly rentals is $25,000 × 4 = $100,000
Yearly depreciation is $2,000,000 ÷ 25=$80,000
Increase in earnings is therefore ;
$100,000 - $80,000 = $20,000
Due to the above, it is evident that earnings would increase meaning that acquiring the office space and the leasing the office space to a lesse was not a profitable deal.
