Answer:
The answer is: The owner's revenue will rise because newspaper demand is price inelastic.
Explanation:
Although the question doesn't specify the price elasticity of newspapers, different papers and essays around the world concluded that it is very inelastic. So an increase in the price of newspapers will decrease the quantity demanded of news papers in a very small proportion. So it is safe to say that if the owner of the newspaper stand raises the price of newspapers, his total revenue will increase since its demand is price inelastic.
