A) Mark up is the amount of profit added on to the cost of a product or service to give selling price. A mark up is usually expressed as a percentage. The relation between the mark up & the elasticity of demand is given by the following equation.

MU = - 1/ (1+e)

Where, MU - refers to the mark up
e - refers to the elasticity of demand.
When the elasticity of demand is -3, then the mark up can be calculated as,
MU = - 1/ (1-3)
= -1/-2
= 0.5 or 50%
Thus the mark up is equal to 50%, which implies that, higher the elasticity, lower the mark up.

B) ...
