Gerken Company concluded at the beginning of 2021 that the company's ownership interest in DillCo had increased to the point that it became appropriate to begin using the equity method to account for the investment. The balance in the investment account is $62,000 at the time of the change, and accountants working with company records determined that the balance would have been $99,000 if the account had been adjusted for investee net income and dividends as prescribed by the equity method. After implementing the change to the equity method, if financial statements were prepared: a. Net income and retained earnings will be higher by $85,000.
b. The accounts will be unchanged, because no adjustment is necessary.
c. Net income and retained earnings will be higher by $15,000.
d. Net income will be unchanged, and retained earnings will be higher by $15,000.

Jenny​ walters, who owns a real estate​ agency, bought an old house to use as her business office. she found that the ceiling was poorly insulated and that the heat loss could be cut significantly if six inches of foam insulation were installed. she estimated that with the​ insulation, she could cut the heating bill by​ $80 per month and the​ air-conditioning cost by​ $70 per month. assuming that the summer season is three months​ (june, july, and​ august) of the year and that the winter season is another three months​ (december, january, and​ february) of the​ year, how much can jenny spend on insulation if she expects to keep the property for five​ years? assume that neither heating nor​ air-conditioning would be required during the fall and spring seasons. if she decides to install the​ insulation, it will be done at the beginning of may.​ jenny's interest rate is​ 6% compounded monthly.
