Suppose there are 1,000 hot pretzel stands operating in New York City. Each stand has the usual U-shaped average-total-cost curve. The market demand curve for pretzels slopes downward, and the market for pretzels is in long-run competitive equilibrium.

Draw the current equilibrium, using graphs for the entire market and for an individual pretzel stand.

Consider the flow field represented by the stream function $\psi=x^6-15 x^4 y^2+15 x^2 y^4-y^6$. Is this a possible two-dimensional, incompressible flow? Is the flow irrotational?

A thin metal plate is insulated on the back and exposed to solar radiation on the front surface. The exposed surface of the plate has an absorptivity of 0.7 for solar radiation. If solar radiation is incident on the plate at a rate of $550 W/m^2$ and the surrounding air temperature is $10^\circ C,$ determine the surface temperature of the plate when the heat loss by convection equals the solar energy absorbed by the plate. Take the convection heat transfer coefficient to be $25W/m^2 \cdot K,$ and disregard any heat loss by radiation.

Instructions (Round answers to the nearest cent.)

• a. Prepare the journal entries to record the following transactions. (1) The issuance of the bonds on June 30, 2017. (2) The payment of interest and the amortization of the premium on December 31, 2017. (3) The payment of interest and the amortization of the premium on June 30, 2018. (4) The payment of interest and the amortization of the premium on December 31, 2018.
• b. Show the proper balance sheet presentation for the liability for bonds payable on the December 31, 2018, balance sheet.
• c. Provide the answers to the following questions. (1) What amount of interest expense is reported for 2018? (2) Will the bond interest expense reported in 2018 be the same as, greater than, or less than the amount that would be reported if the straight-line method of amortization were used? (3) Determine the total cost of borrowing over the life of the bond. (4) Will the total bond interest expense for the life of the bond be greater than, the same as, or less than the total interest expense if the straight-line method of amortization were used?

Telemarketing At a telemarketing firm, an employee is paid $12 an hour plus$0.75 for each call completed. During an 8-hour day, the employee's compensation was $159.75 . How many calls did the employee complete?

A discount pass for a bridge costs $30 per month. The toll for the bridge is normally$5.00, but it is reduced to $3.50 for people who have purchased the discount pass. Determine the number of times in a month the bridge must be crossed so that the total monthly cost without the discount pass is the same as the total monthly cost with the discount pass.
