Hi, Would you mind answering Both of these answers, please? Thank you.

1. The Consolidated Oil Company must install antipollution equipment in a new refinery to meet federal clean-air standards. Four design alternatives are being considered, which will have capital investment and annual operating expenses as shown below. Assuming a useful life of 8 years for each design, no market value, a desired MARR of 10% per year, determine which design should be selected on the basis of the PW method. Confirm your selection by using the FW 2. The following data have been estimated for two mutually exclusive investment alternatives, A and B, associated with a small engineering project for which revenues as well as expenses are involved. They have useful lives of four and six years, respectively. If MARR =10% per year, show which alternative is more desirable by using FW equivalent-worth methods, and an analysis period of six years is used (co-terminated assumption)
