Answer: $107,500
Explanation:
There is an "Exclusion of gain on sale of home" provision by the IRS that allows for a single tax payer to exclude up to $250,000 from the sale of their primary home. A home qualifies as primary if the owner has lived in it for 2 years or more so Steve's home here is a primary home. 
The gain he received was:
= 705,000 - 347,500
= $357,500
From this gain, $250,000 can be excluded so total gain recognized:
= 357,500 - 250,000
= $107,500
 
        
             
        
        
        
Answer:
Projects D and E should be purchased.
Explanation:
since the firm's capital structure is 60% debt and 40% equity, it can pursue up to 2 projects. Only projects D, E and F have an internal rate of return higher than the company's WACC, so project G is discarded immediately. 
Since projects D and E have a higher IRR, they should be selected. 
- project D: $70,000, IRR = 18%, debt = $42,000, equity = $28,000
- project E: $85,000, IRR = 15%, debt = $51,000, equity = $34,000
- total equity invested = $62,000
