How would I solve this question?: suppose demand for cigarettes is inelastic and supply of cigarettes is elastic. Who would bear the larger share of the burden of a tax placed on cigarettes? Include supply and demand diagram that depicts situation

Under which circumstances does line tax burden fall entirely on consumers?

The price of coffee rose sharply last month, while the quantity sold remained the same. Five people suggest various explanations: Leonard: Demand increased, but supply was perfectly inelastic. Sheldon: Demand increased, but it was perfectly inelastic. Penny: Demand increased, but supply decreased at the same time. Howard: Supply decreased, but demand was unit elastic. Raj: Supply decreased, but demand was perfectly inelastic. Who could possibly be right? Use graphs to explain your answer.

Describe the general appearance of a demand or a supply curve with infinite elasticity.
