manufactures small electronic components called diodes. Each diode is worth $1.50. Plant A produced 4443 diodes and Plant B produced 5557 diodes. The supervisor was asked what the total value of all the diodes was. The supervisor immediately responded "$15,000." The supervisor would not have been able to compute the value so quickly if he had to multiply $1.50 by 4443 and then add this to the result of $1.50 times 5557. Explain how you think the supervisor got the answer so quickly? $1.50

Question
### Manufacturing Problem

**Context:**  
A company manufactures small electronic components called diodes. Each diode is worth $1.50. There are two production plants:

- **Plant A** produced 4,443 diodes.
- **Plant B** produced 5,557 diodes.

**Problem Statement:**  
The supervisor was asked to calculate the total value of all the diodes. Without performing detailed calculations, the supervisor quickly responded with a total value of **$15,000**. The question is how the supervisor arrived at this total so promptly when one would typically multiply the number of diodes produced by each plant by $1.50 and then sum the results.

**Objective:**  
Explain the reasoning behind the supervisor's rapid computation of the total value. What shortcut or logical reasoning might the supervisor have used to arrive at the solution quickly?

**Considerations:**  
Calculate the actual total value using the following steps and consider any estimation techniques:

1. Calculate the total number of diodes from both plants:  
   - Total diodes = 4,443 (Plant A) + 5,557 (Plant B).
  
2. Calculate the total value using the unit price:  
   - Total value = Total diodes × $1.50.

3. Compare with the supervisor’s estimated total of $15,000 and explore possible estimation methods or shortcuts.

Expert Solution
Step 1

Given that : value of each diode = $ 1.50

plant A reduces number of  diodes = 4443

Plant B reduces number of diodes = 5557

To find : How the supervisor find the total value of diodes as $ 15000.
