A) (Look at graph) While it doesn’t make complete sense to connect the points because the # of customers is not a continuous variable, it is quite common to see continuous graphs drawn in such situations. B) For each increase of $2 in price, there is a decrease of 15 customers. The points fall exactly on a line. C) The pattern suggests that if the price is $16, there will be 30 customers. A price of $20 will attract NO customers. A price of $2 will attract 135 customers. B) It does make some sense to connect the points because prices could be offered at just about any dollar amount (including partial dollars as fine as $.01) C) The pattern shows increasing income as price increases, but only to a point. Then the price-induced decrease in customers becomes a stronger factor in shaping income than the increase in price itself. The pattern in the data makes sense because if the price goes too high, the number of customers willing to pay this price will decrease. Hence, the income will decrease.
