![The quantity demanded each week \( x \) (in units of a hundred) of the Mikado digital camera is related to the unit price \( p \) (in dollars) by the demand equation:
\[
x = \sqrt{400 - 5p} \quad (0 \leq p \leq 80).
\]
(a) Is the demand elastic or inelastic when \( p = 40 \)?
- ○ elastic
- ○ inelastic
When \( p = 70 \)?
