You took a $800 cash advance by using checks linked to your credit card account. The bank charges you a 1% cash advance fee on the amount borrowed with no grace period on cash advances. How much money is required to pay off the balance in full after one month at 13% APR?

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.
