An average size store having 16,800 square feet (A=168),
will utilize 66,000 gallons of water at a price of $0.40 per thou-
sand. A store twice as large will utilize about 120,000 gallons of
water, or not quite twice as much. A store half the size of the
average, will utilize more than half the quantity of water util-
ized by the average size store (Figure 2).
 The demand is inelastic for all prices less than $1.33 per
thousand gallons. This means the demand by grocery stores is
generally more inelastic than is the demand by department
stores. Increasing the price from $0.40 to $0.80, for example,
leads to a greater response by the department stores as com-
pared to that by the grocery stores. As with department stores,
these demand curves are illustrative of a relatively long run
period.
