What is the present value of depreciation tax savings associated with this equipment?

A certain piece of equipment costs $32 million plus an additional $2 million to install. This equipment qualifies under the 5 year MACRS category. For a firm that discounts cash flows at 12 percent and faces a tax rate of 34 percent, what is the present value of the depreciation tax savings associated with this equipment?

By how much would that number change if the firm could treat the $2 million installation cost as a deductible expnese rather than include it as part of the depreciable cost of the asset?
