Question

a retailer finds that he can sell 2000 dvd players per month at R300. if he reduces his price to R250 per unit his sales increase to 2400 per month. find the demand relation, assuming it to be linear.

Answer 1

Demand =
D(300) + [D(300) - D(250)] / [300 - 250] * (Price - 300) =
2000 + [-400] / [50] * (Price - 300) =
2000 + [-8] * (Price - 300) =
2000 + 2400 - 8 * Price =
4400 - 8*Price

Answer 2

once you are going to lose funds advertising your place, i could advise renting it out under industry. So if leases are going for $1200, hire it out for one thousand to generate condominium activity. you will basically could desire to make up $500 according to month, which continues to be extra effectual than paying $1500, AND somebody is paying off 2/3 of your very own loan for you until the industry recovers.

Answer 3

D - 2,000 = (2,000 - 2,500)(x - 300)/(300 - 250)
D - 2,000 = 3,000 - 10x
D = 5,000 - 10x
