It’s MATH TIME! Please take out your homework (ACE 6, 22, 23)… …and your DEAR book to read.
Homework answer #6 c & D d. If the truck is driven for less than ~89 miles, East Coast Trucks is the company to use. If it is driven more than 89 miles, Philadelphia Truck Rental is the better choice.
Homework answer #22 a • 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.
Homework answer #22 B &C • 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.
Homework answer #23 B • 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)
Homework answer # 23 c • 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.

While you explore… • Which variable depends on the other? • As the independent variable increases, what happens to the dependent variable? • Will the increase or decrease be constant or will it slow down or speed up in places? • How will the change appear in the graph moving from left to right?
Work individually for a few minutes on problem 2.3 A & B to match the graphs… • Book p. 34 • Do it in the “Problems/ ACE” section • Title it “Problem 2.3”
