Geller Florist Inc. completed the following transactions during 2015: 

Purchased a $200,000 warehouse with $50,000 in cash and a $150,000 mortgage from a bank. I raised $100,000 from the sale of new shares to investors. The cash was used to buy land to grow tulips. He sold an old building for $50,000 (and suffered a loss on the sale of $5,000) and used the cash to buy a new truck. 

What is the net impact of these transactions on Geller's cash from investing activities during 2015?
