On Jan. first, 2018, Snuff Company accepts 60000 non-interest bearing note from a customer for the sale of goods. The note is to be paid in 3 equal installments every Dec. 31st (first payment on Dec. 31, 2018). An assumed interest rate of 10% is implied. Round installment payments to the nearest dollar.

pt 1: Determine the PV of the note. Show all computations or calculator imputs.

Problem B

At the beginning of 2018, Pineapple Inc. acquired a machine by issuing a $14,400 3-year non interest-bearing note. The machinery had a book value of $4,350 in the seller's book. Although Pineapple felt that it could get a similar machine for less than $14,400, it was satisfied, since it would normally have to borrow at 10%. The principal of the note is to be repaid at $4,800 per year, beginning on 12/31/2018.

Required:

Prepare all the journal entries in books of Pineapple Inc. relating to this note in the year 2018. Specifically, what do you use as the interest rate in calculating present value of the machinery?

A 44.39 gram sample of iron is heated in the presence of excess oxygen. A metal oxide is formed with a mass of 63.46 g. Determine the empirical formula of the metal oxide. Enter the elements in the order Fe, O empirical formula =

The size effect, value effect and day of the week effect represent three empirical challenges to market efficiency hypothesis. Drawing from empirical research evidence, explain how these anomalies challenge the market efficiency hypothesis.

According to empirical evidence, nominal interest rates are procyclical. They rise when the economy booms and they fall during recessions. Is this empirical evidence consistent with DAD-DAS models? Explain and use graphs to illustrate your answer.

A. A 13.98 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 20.85 grams of CO₂ and 6.402 grams of H₂O are produced.
