Answer:
The company will save 16 million dollar per year (till 5 years).
Step-by-step explanation:
The saving can be easily calculated by subtracting tax paid after charging depreciation from tax paid if no depreciation is charge.
Tax Paid if no depreciation is charge
= $ 50 * 40% = $ 20 Million -A
Tax Paid if depreciation is charge
= ($ 50- $ 40") * 40% = $ 4 Million -B
" 200/5 =40
Tax saving = A-B = $ 16 Million per year
