This is the question
A company buys a computer for $125,000 and houses it in a specially constructed suite at a cost of $20,000.
a) If the computer depreciates at 30%(reducing balance) and the suite appreciates at 6%(compound),what is the book value of suite and computer after 5 years?
b) Taking computer and suites together and using the reducing balance method, what is the overall depreciation rate?
I managed to get the answer to a) which is suite = -$6000, computer = $30,012.50
I do not know how to solve b)
Can someone please help me thanks
