Assume that the demand of chocolate of a local producer is given by q = 9-√p in hundreds of kilograms, where p = [0, 81] is the price of a kilogram in USD. 1. Compute the elasticity of the demand as a function of p, and find where it is unit elastic, elastic, and inelastic. 2. Compute the revenue R(p) in USD as a function of p. Careful of units! 3. Compute R'(25). Interpret this quantity. Remember to write down units. 4. What is the sign of R'(25)? Considering what you obtained in Question 1, does this make sense? Why? 5. Now, compute the revenue R(q) in USD as a function of q. Careful of units! 6. Compute the marginal revenue Rm(q). 7. Compute Rm (4). Interpret this quantity. Remember to write down units. Since q= 4 corresponds to p= 25, why is the result different from Question 3?

Exercise IV: Revenue functions
Assume that the demand of chocolate of a local producer is given by q = 9 - √p in
hundreds of kilograms, where p = [0, 81] is the price of a kilogram in USD.
1. Compute the elasticity of the demand as a function of p, and find where it is unit
elastic, elastic, and inelastic.
2. Compute the revenue R(p) in USD as a function of p. Careful of units!
3. Compute R'(25). Interpret this quantity. Remember to write down units.
4. What is the sign of R'(25)? Considering what you obtained in Question 1, does this
make sense? Why?
5. Now, compute the revenue R(q) in USD as a function of q. Careful of units!
6. Compute the marginal revenue Rm(q).
7. Compute Rm (4). Interpret this quantity. Remember to write down units. Since
q= 4 corresponds to p= 25, why is the result different from Question 3?
