The College of Business is deciding between two photocopier options. The first is to lease a high-end machine for $8,400/year. The lease is all-inclusive so 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. a. Which option is preferred if the annual copy volume is expected to be 270,000? b. What if the copy volume is reduced to 240,000? C. At what volume is the College indifferent between the two options?

A. The second photocopier is preffered with only costing $10,400 a year wereas the High-end one cost $11,100 per year.

B. The second choice would still be preffered due to the fact that it is still cheaper. The total cost for the second one is $9,800 and the high-end is a total of $10,800.

Step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
