Gain on sale of equipment 8,000
Purchase of Will Bonds ($300,000 face value) 275,000
Proceeds from sale of machinery 300,000
Dividends paid 50,000
Proceeds from sale of treasury stock 200,000

Net cash from investing and financing activities = 50,000 and 160,000 and the gain on sale of equipment should be added to net

I'm not sure what you (or they) are asking here? Is the problem asking you to do a Cash Flow Statement?

Using the information provided; what amount should be reported from investing activities and what amount should be reported from financing activities.

Okay, the cash flow statement is divided into three parts: changes in cash generated by operations, changes due to investing, and changes due to financing. Your problem is asking you to determine how each of those items would be classified.

I couldn't quite figure out how you got your 50,000 and 160,000, but I just looked at it briefly. Why don't you identify after each actifity if you think it is net operations, financing or investing?
