<em><span>Решение:</span></em>
<span>Линейная функция имеет вид: </span>
<span>Q = а — </span><span>b</span><span>Р = 0,2/(-0,1) * 30/500 = -2*0,06 = - 0,12</span>
<span>K = -0,12*500/30 = -2</span>
<span>QD</span><span>= -2*30 + а = 500</span>
<span>а = <span> </span>560</span>
<span>Новая функция </span><span>QD</span><span>=560 – 2Р. </span>
<span>QS = 400 + 3,33P.</span>
