For the following demand function, find a. E, and b. the values of q (if any) at which total revenue is maximized. q=35,300 - 4p a. Determine the elasticity of demand, E. E = (Type an expression using p as the variable.) b. Determine the value of q that maximizes the revenue. Select the correct choice below, and if necessary, fill in the answer box within your choice. A. Total revenue is maximized at about q=| (Round to the nearest whole number as needed.) B. No values of q maximize total revenue. For the following demand function, find a. E, and b. the values of q (if any) at which total revenue is maximized. p=400e-0.6q a. Find the elasticity of demand (E) in terms of q. E(q)= b. Determine the value of q that maximizes the revenue. Select the correct choice below, and if necessary, fill in the answer box within your choice. A. Total revenue is maximized at about q= (Round to the nearest whole number as needed.) B. No values of q maximize total revenue. The short-term demand for crude oil in Country A in 2008 can be approximated by q = f(p) = 2,143,525p- 0.04, where p represents the price of crude oil in dollars per barrel and q represents the per capita consumption of crude oil. Calculate and interpret the elasticity of demand when the price is $95 per barrel. The elasticity of demand for oil is (Type an integer or a decimal.) What is the elasticity of demand for oil when the the price is $58 per barrel? (Type an integer or a decimal.) Interpret the elasticity of demand. Choose the correct answer below. OA. The demand is elastic, so as price increases, revenue increases B. The demand is inelastic, so as price increases, revenue increases. OC. The demand is elastic, so as price increases, revenue decreases. D. The demand is inelastic, so as price increases, revenue decreases.
