second question
The demand for petrol rises from 500 to 600 Barrels when the price of a particular scooter is reduced from ETB 25,000 to ETB 22,000. Find out the cross elasticity of demand for the two. What is the nature of their relationship?
With reference to price elasticity of demand, answer the following questions: 3.4.1 Indicate what the two (2) main determinants are that price elasticity of demand depends on. (2) 3.4.2 With the aid of a diagram (draw the diagram), illustrate and explain what a linear demand curve is, where exactly the top of the curve is and where the bottom of the curve is, and how elasticity values (coefficients) vary on the curve from being infinitely (perfectly) elastic to unit elastic and finally to completely (perfectly) inelastic.

The last payment for the loan occurs on 1 July 2044. For the next question, we will refer to 2044 as the "final year". Type in the "final year" below (i.e. if the last payment occurs in 2031, type in 2031).
Calculate the equivalent effective monthly rate. Give your answer as a percentage to 4 decimal places, and do NOT include a percentage sign
The interest rate for the loan is 5.6% p.a. effective. Calcualte the equivalent nominal annual rate compounding monthly. Give your answer as a percentage to 4 decimal places, and do NOT include a percentage sign.
