Pricing

BPP Kit 2016/2017 Question 72 The answer should be 120, not 110. Where did they get the $1 increase on price. I'm assuming it's a mistake.

This is a Paper F5 question - you have posted in the F9 forum! The BPP answer is correct. For every $5 change in price, the demand changes by 10,000 units. That is exactly the same as saying that for every $1 change in price, the demand changes by 10,000/5 = 2,000 units. However you write it, 'b' in the equation is still equal to 0.0005
