A weekly income of a clerk was increased from N100 to N125 as a result of his promotion in the office. He is able to purchase 300 leaves of bread instead of 200 per week (1) Calculate the co-efficient of his income elasticity of demand. (2) Is the demand elastic or inclastic? Why? (3) What kind of goods is bread to the consumer?

The Stopdecay Company sells an electric toothbrush for $25. Its sales have averaged 8,000 units per month over the past year. Recently, its closest competitor, Decayfigh ter, reduced the price of its electric toothbrush from $35 to $30. As a result, Stopde cays sales declined by 1,500 units per month.
