5. You have 37 coins that are nickels, dimes, and
pennies. The total value of the coins is $1.55. There are twice as
many pennies as dimes. Find the number of each type of coin in the
bank.
Answer: Let n be the number of nickels, d be the number
of dimes, and p be the number of pennies. The system
is
1st equation:...
Let yp(y) be the C(2) inverse demand function facing a monopoly, where y++ is its rate of output, and let yC(y) be the C(2) total cost function of the monopoly. Assume that p(y)>0, p'(y)<0, and C'(y)>0 for all y++, and that a profit maximizing rate of output exists. Total revenue is therefore given by R(y)=p(y)y. Given that question uses an inverse demand function, the elasticity of demand, namely (y), is defined as (y)= 1/p'y p(y)/y. Why is (y)<0? Prove that...
