Answer:
The question is incomplete, the option include:
- $20,000 decrease.
- $45,000 decrease.
- $80,000 decrease.
- <em>$160,000 decrease. is Correct</em>
- $320,000 decrease.
Explanation:
1. In 2019 the number of finished units with internal faults = $400,000 completed units * 0.05 = $20,000.
2. In 2020 the number of finished units with internal faults = $20,000* (1 -0.1) = $18,000.
3. In 2020, the projected cost of internal failure= $18,000 * $80= $1,440,000;
4. In 2019 the expense of internal failure= $20,000 * $80 = $1,600,000.
5. Projected shift in the cost of internal failure = <em><u>$1,600,000 - $1,440,000 = decrease of $160,000</u></em>
