4. A company introduced a new product to the market in the first month of the year which was supported by the corresponding advertising campaign and showed steady growth in the following months. The initial price was set at a level of 30% above average cost (MK). The company's goal is to cover its overheads and achieve maximization in profits and that's why I'm wondering i if the price of 7,5 is optimal. With the continuous growth of sales, the company conducted market research and found that the elasticity of demand towards the price is -3. The formula for calculating the demand elasticity to the price is given: T = [-MK/(T-MK)] - 1

Sales (tons) and cost (mm. (EUR) For the next 3 months they are estimated as follows:

	JANUARY	FEBRUARY	MARCH
Sales (volume)	2.250	2.500	2.750
Raw materials	1.400	1.550	1.700
Work	3.350	4.050	4.950

Other industrial costs	3.000	3.075	3.150
Administrative expenses	2.150	2.150	2.150
Electric - Heating	450	475	300
Other overheads	2.250	2.200	2.200
TOTAL EXPENSES	12.600	13.500	14.450

a ) Assuming the price may be changing, calculate the price per month . b) What percentage mark-up is exported for each month?

c) What other factors should the company take into account besides price and sales decisions?
