The Johnsons have a second home that was available to rent for four full weeks (28 days) during the summer. Of the twenty-eight days, the Johnsons rented it to unrelated tenants for 16 days at fair market value. In addition, the Johnsons rented the home to the Florians for four days. Because they are family friends, the Florians only paid half the market rate for the rent. The Johnsons also rented the home for five days to the Smiths. The Smiths paid full fair market value rent even though they are related to the Johnsons. How many days did the Johnsons use the home for rental purposes during the year

16

Explanation:

The Johnsons only rented the second home to unrelated tenants during 16 days, and that is the period that counts for rental purposes.

When you rent a property to relatives or family members, it doesn't count as rental purpose, it counts as personal use even if they paid you rent. If you rent the property for less than fair market value, it also counts as personal use.

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
