7-14

Fixed cost is $30,000, and variable cost is $4 per unit. What is the total cost for 20,000 units?

Fixed cost is $30,000, and variable cost is $2 per unit for 10,000 units. If fixed costs increase by 10%, how much will total cost increase?

Total cost is $60,000 to make 20,000 units. Fixed cost is $20,000. What is the variable cost per unit?

We have customers in three locations at grid locations (2,6), (5,1), and (2,2). Each area needs the same quantity. Where is the center of gravity?

We have two customers; one is at coordinates (6,2) and has 200 units of demand, and the other is at (3,4) with 800 units of demand. What is the center of gravity (round to the nearest whole number coordinates)?

Problem 5-6

A real estate agent is considering changing her cell phone plan. There are three plans to choose from, all of which involve a monthly service charge of $20. Plan A has a cost of $.44 a minute for daytime calls and $.19 a minute for evening calls. Plan B has a charge of $.54 a minute for daytime calls and $.15 a minute for evening calls. Plan C has a flat rate of $80 with 225 minutes of calls allowed per month and a charge of $.40 per minute beyond that, day or evening.

a.

Determine the total charge under each plan for this case: 130 minutes of day calls and 50 minutes of evening calls in a month. (Do not round intermediate calculations. Round your answer to 2 decimal places. Omit the "$" sign in your response.)

Cost for Plan A $

Cost for Plan B $

Cost for Plan C $

c.

If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal? (Round each answer to the nearest whole number.Include the indifference point itself in each answer.)

Plan A is optimal from zero to minutes. Plan C is optimal from minutes onward.

d.

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? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places. Omit the "%" sign in your response.)
