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
Truck Rental is the better
choice.
 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.
