4x = $70 . x represents the cost of each ticket per person. multiply that by 4 to get $70.
Idk sorry I’m stuck in an iready lessssssooooooonnnn. Ahahahahah
Given:
Demand curve: q = (400-p)^2 / 100
where:
q = the number of copies the publisher can sell per week at $p
p = price of the copies
a) Find the price elasticity of demand when the price is set at $40 per copy
substitute p = $40
q = (400-40)^2 / 100
Therefore,
q = 1296
slope, m = (y2-y1)/(x2-x1) = (2-(-4))/(4-1) = 6/3 = 2
so, your answer is 2
0 is the answer Hope this helps
