Atall starbucks coffee costs $1.65 a day. of the bank’s daily interest rate is 0.01%, compounded daily, and if the starbucks price never changed, what would an endless, inheritable free subscription to one starbucks coffee per day be worth today

This problem requires the equation for perpetuity. Since the problem asks for the present value for an infinite period subscription for one Starbucks coffee, the equation would be PV= A/i wherein A is the price of 1 cup of coffee which is $1.65. The interest rate can be computed by using the equation i= (e^rate)-1. The interest rate computed is 1.0001x10^-4. The present value is $16499.18. 

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.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
