I do not even know where to start with this one...Suppose that Petrobas assumes zero salvage value for their "Equipment and other assets." For each $100 in new asset investments, what is the annual amount of depreciation expense charged to the income statement?

On the income statement under "Equipment and other assets" is lists the estimated life in useful years as 3 to 30.

Cost is 119,999,208

Accumulated Depreciation is (55,854,051)

Net is 64,145,157
