Expert's answer

PED = -1.2 Ei = 3.0. Price of motor vehicles increases by 5%, income increases by 3%.

a. If sales of the vehicles are 10 million this year, then we expect the automaker to sell 5%*1.2 = 6% more or 10.6 million next year.

b. If the automakers wish to increase sales by 5% next year, then they should increase the price of motor vehicles by 5%/1.2 = 4.17%.

a. If sales of the vehicles are 10 million this year, then we expect the automaker to sell 5%*1.2 = 6% more or 10.6 million next year.

b. If the automakers wish to increase sales by 5% next year, then they should increase the price of motor vehicles by 5%/1.2 = 4.17%.
