Assume the government puts a tax of $3$ on each apple sold. $[$We never defined the currency units in Check$-$in Exam #$1,$ so you can ignore them.$]$

$$

As a reminder, the equilibrium price for apples was $90($again$,$ unitless$),$ and the equilibrium quantity was $6,300.$ In addition, at the equilibrium, the elasticity of demand $($D$)=-0\mathrm{.}43,$ while the elasticity of supply $($S$)=2\mathrm{.}00.($You can go and check the answer key from Check$-$in Exam #$1$ if you$$d like. Please do NOT work out that these are the right answers $$ I$$m telling you they are.$)$
