Answer:
a. Inelastic, b. Raise
Step-by-step explanation:
a. When the price rises by 10%, the quantity demanded falls only by 5%, that is, falls by less than proportionate amount. It is proof that the demand is inelastic.
b. If the company wants to raise its revenue, it must raise its price. It will lead to less than proportionate fall in demand, leading to an increase in total revenue.
