Answer:

A.  

0.833

The College of Business is deciding between two photocopier options. The first is to lease a high-end machine for $8,400/year. T
Sedaia [141]

Answer:

Instructions are listed below.

Explanation:

Giving the following information:

The first is to lease a high-end machine for $8,400/year.The only additional costs are the cost of paper, which is $0.01/sheet.

The other option is to purchase a machine. The cost is $5,000 and the per sheet cost increases (toner, maintenance) to $0.02.

First, we need to determine the total cost formula for each option:

Option 1:

Total cost= 8,400 + 0.01x

Option 2:

Total cost= 5,000 + 0.02x

A) Volume= 270,000

Option 1:

Total cost= 8,400 + 0.01*270,000= $11,100

Option 2:

Total cost= 5,000 + 0.02*270,000= $10,400

Option 2 is the cheapest.

B) Volume= 240,000

Option 1:

Total cost= 8,400 + 0.01*240,000= $10,800

Option 2:

Total cost= 5,000 + 0.02*240,000= $9,800

Option 2 is the cheapest.

C) To determine the indifference point, we need to isolate X:

8,400 + 0.01x= 5,000 + 0.02x

3,400= 0.01x

340,000=x

The indifference point is 340,000 paper sheets.
