. Revenues and the statement of cash flows. Joan started a catering business on the first day of July. She catered 10 parties in July and earned \(\$ 300\) for each party. Most of her customers paid her at the time she provided her services, but one customer, George Smith, asked Joan to send him a bill and he would then send her a check.
