all three questions need an answer please:)

Silicon Graphics is considering a project that has the following cash flow and weighted average cost of capital (WACC) data. Determine the project's NPV. WACC: 12.00% Year (t) and cash flows (t=0) -$1,100 (t=1) $400 (t=2) $390 (t=3) $380 (t=4) $370 (t=5) $360 Answer choices: $211.32 $401.58 $277.94 $366.65 Global Transport is considering a new project with relevant data shown below. The equipment that would be used has a 3-year tax life, would be depreciated by the straight-line method over its 3-year life, and would have a zero salvage value. No new working capital would be required. Revenues and other operating costs are expected to be constant over the project's 3-year life. What is the project's NPV? Hint: First, find the annual after-tax cash inflow for the project Risk-adjusted WACC 10.0% Net investment cost (depreciable basis) $90,000 Straight-line deprec. rate 33.3333% Sales revenues, each year $75,000 Operating costs (excl. deprec.), each year $35,000 Tax rate 35.0% Answer choices: $770 $1,604 $1,253 $1,932 Digital Solutions Inc. has a capital structure of 40% debt and 60% equity, its tax rate is 35%, and its levered beta, bl, is estimated to be 1.18. A financial analyst for Digital Solutions wants to estimate what the company's unlevered beta, bu, would be if it used no debt. Assume that the analyst will use the Hamada equation to determine the unlevered beta, what would be the estimate for bu? Note: bu = b_/[1 + (1 - T) x (D/E)]. Answer choices: 0.99 0.76 0.92 0.82
