Questions:
1. mortgage note for 80,000 was issued for cash
2. a building was constructed for 207,000
3. 5,000 shares of common stock were issued at $28 in exchange for the bonds payable
(Bonds pay - 140,000)


My Answers:

Financing Activities:
Cash received from stock issuance 140,000
Decrease in bonds-pay (140,000)
Increase in mortgage note 80,000

Investing Activities:
Cash paid for building construction (207,000)

I'm not exactly sure what the questions are but you seem to be on the right track.
The Journal Entries for the transactions would be:
1.) Debit Cash $80000 & Credit Mortgage Note 80000
2.) Debit Fixed Assets 207000 & Credit Accounts Payable (cash is not specified)
3.) Debit Cash $140000 & Credit Bonds Payable $140000

Hope that helps
