BlackZzzverrR [31]

Answer:

a. Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month.

  • Cost for Plan A = ($0.41 x 120) + ($0.16 x 40) + $20 = $ 75.60
  • Cost for Plan B = ($0.51 x 120) + ($0.15 x 40) + $20 = $ 87.20
  • Cost for Plan C = $80 + $20 = $100

b. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal?

  • If the agent will use the service only for daytime calls, Plan A is better if the agent uses 195 minutes maximum. If the agent expects to use 196 or more minutes, then Plan C is better.

c. Suppose that the agent expects both daytime and evening calls. At what point (i.e., percentage of total call minutes used for daytime calls) would she be indifferent between plans A and B?

  • Plan A charges 10¢ less per daytime minute, while plan B charges 1¢ less for evening minutes, that means that the proportion of daytime calls should be 1/11, while the proportion of evening calls should be 10/11.

From time to time, various groups clamor for import restrictions or tariffs on foreign-produced goods, particularly automobiles.
Misha Larkins [42]

Tariffs can be helpful if the imports are unfairly cheaper than the domestic counterparts. This would level the playing field and help the domestic companies compete more effectively.

Tariffs can be harmful for consumers because there is strong possibility that the increased costs will raise consumer prices.
