From an economic point of view, this will

shift the demand curve leftward for tanning.

shift the demand curve rightward for tanning.

shift the supply curve rightward for tanning.

move down along the demand curve for tanning.

##### Explanation:

The excise tax lowers demand because consumers must now pay a higher tax in addition to the price they pay for the good. People will tan less because they now have to factor in the extra cost. This will be shown as a leftward shift of the demand curve.
