d$.$ Following the demand function$($curve$)$ in $($b$.),$ what is the elasticity of demand of organic carrot when $P_0=5?$ What if $P_o=10?$

e$.$ Now given the supply for organic carrot:

$Q_o^S=5P_o$

Graph it with the demand curve in $($b$.),$ Find the equilibrium quantity $Q_o^e$ and price $P_o^e.$

f$.$ Graph the demand curve like $($b$.),$ yet income increases to $I=20.$ What is a direction the demand curve shifts in this case? what is the new equilibrium quantity $Q_0^{e\text{'}}$ and price $P_0^{e\text{'}}.$

g$.$ What happens to the demand for organic carrots when the price of conventional carrots increases?

Are organic and conventional carrots complements or substitutes? How do you know?

h$.$ Following $($d$.),$ Are organic carrots a normal or an inferior good? How do you know?
