q =
768 | ||
|
− 1, for p > 0.
Find and explain the meaning of the instantaneous rate of change of demand with respect to price when the price is as follows.
(a)
$16
Interpret the instantaneous rate of change.
If price increases by the absolute value of this amount, the demand will drop by 1 unit. If price decreases by the absolute value of this amount, the demand will drop by 1 unit. If price decreases by $1, the demand will drop by the absolute value of this number of units. If price increases by $1, the demand will increase by the absolute value of this number of units. If price increases by $1, the demand will drop by the absolute value of this number of units.
(b)
$64
Interpret the instantaneous rate of change.
If price increases by the absolute value of this amount, the demand will drop by 1 unit. If price decreases by the absolute value of this amount, the demand will drop by 1 unit. If price decreases by $1, the demand will drop by the absolute value of this number of units. If price increases by $1, the demand will increase by the absolute value of this number of units.
