Which organization works to establish global standards for communications and information exchange?

The international organization for standardization or ISO works to found global standards for communications and information exchange. Mainly between its activities is the widely recognized ISO/OSI reference model which describes standards for the communication of computers linked by communications networks. The ISO is not an acronym somewhat it is consequent from the greek word ISOS which means equal and is the root word of the prefix ISO. 

1. Greater than 30,000 but less than or equal to 35,000

2. Greater than $370,000 but less than or equal to $375,000

3. A) Buy the part.

4. A) Less than or equal to $20,000.

Explanation:

Total cost = Fixed cost + (Variable costper unit * Volume

Let the volume be x

TC buy = 700 + 12.25x

TC make = 100,000 + 9.00x

TC buy = TC make

700 + 12.25x = 100,000 + 9.00x

12.25x - 9.00x = 100,000 - 700

3.25x = 99,300

x = 99,300 / 3.25

x = 30553.847

x = 30,554 units

The correct answer is "Greater than 30,000 but less than or equal to 35,000"

2. TC buy = 700 + 12.25x

TC buy = 700 + (12.25 * 30,554)

TC buy = $700 + $374,287

TC buy = $374,987

TC make = 100,000 + 9.00x

TC make = 100,000 + (9.00 * 30,554)

TC make = $100,000 + $274,986

TC make = $374,986.

The correct answer is "Greater than $370,000 but less than or equal to $375,000"

3. TC buy = 700 + 12.25x

TC buy = 700 + (12.25 * 25,000)

TC buy = $700 + $306,250

TC buy = $306,950

TC make = 100,000 + 9.00x

TC make = 100,000 + (9.00 * 25,000)

TC make = $100,000 + $225,000

TC make = $325,000.

Calculating cost in both the cases, we see that in 1st case it is $306950, which is less than making in-house. Thus, Option A, Buy the Part

4) Cost Savings = $100,000 + (9.00 * 25,000) - $700 - (12.25 * 25,000)

Cost Savings = $325,000 - $306,950

Cost Savings = $18,050

Thus, Option A since it less than or equal to $20000
