As you can tell from the financial statements, 2020 was an especially busy year. Tony and Suzie were able to use the $1.2 million received from the issuance of 100,000 shares of stock to hire a construction company for $1 million to build the cabins, dining facilities, ropes course, and the outdoor swimming pool. They even put in a baby pool to celebrate the birth of their firstborn son, little Venture Matheson. Assume all sales and services are on credit.
