Final answer:
Under the accrual method of accounting, Maroon Orange Gym, Inc should report $420 as gross income in 2015 from the sale of a one-year and a two-year membership, not any of the provided options.
Step-by-step explanation:
The Maroon Orange Gym, Inc. sells memberships and uses the accrual method of accounting. With this method, income is recognized when earned, not when received. For a one-year membership sold for $480, the income is recognized as $40 per month. Similarly, a two-year membership sold for $720 is recognized as $30 per month. When the company sold a one-year membership ($480) and a two-year membership ($720) on July 1, 2015, for the year 2015 (July to December), the income from the one-year membership is $40 x 6 = $240, and from the two-year membership, it is $30 x 6 = $180. Together, this totals to $420 for 2015. Therefore, none of the provided options are correct. In 2015, they should report $420 of the $1,200 received as gross income, with the remaining balance recognized in subsequent periods.
