3. Given the profit function: π = $7,000 + $400Q - $Q2
Where Q is output in units, please determine:
a. the level of output that maximizes profit, and
b. the marginal profit at the output level that maximizes total profit.
4. Seattle Coffee Station is considering selling coffee mugs imprinted with the company log.
Estimates taken from a pilot study suggest the following demand curve: Q = 12,000 – 3,000P
a. How many mugs could Seattle Coffee Station sell at $3.00 each; at$3.50 each?
b. What price must Seattle Coffee Station to sell 2,250 mugs?
c. At what price would quantity be zero?
d. How many mugs should Seattle Coffee Station have ready if it decides to make the project purely
promotional by giving the mugs away?
e. Calculate the point price elasticity at a price of $2.50.
f. What is the arc price elasticity over the range of prices: $2.50 to $2.75 and $2.75 to $3.00.
5. The Fun Center recently reduced the price of two-scoop ice-cream cones from $1.50 each to $1.00
each. The direct response to this change in price was an increase in weekly sales. The estimated
average price elasticity of demand was calculated to be 1.25. Determine if a further $.10 reduction
in price would increase or decrease revenue to the Fun Center. Assume the Ep = -1.25 over the
relevant price range.
