68. A restaurant's best-selling dish is its signature pizza. To bring this pizza to the customers plate, 20 minutes of normal time is required by each worker for which each worker is rewarded a 10 percent allowance. What would be the standard time for preparing a single signature pizza?
Answer: B
The standard time for preparing a single signature pizza is 22 minutes.
To determine the standard time for preparing the signature pizza, we must add the normal time required (20 minutes) to the 10 percent allowance for each worker. This results in a total of 22 minutes.
A) 2 minutes
This option is incorrect as it significantly underestimates the time required to prepare the pizza. The normal preparation time is 20 minutes, which is far greater than 2 minutes.
B) 22 minutes
This option is correct because it accounts for the 10 percent allowance added to the normal preparation time of 20 minutes. The calculation is 20 minutes plus 10 percent of 20 minutes, which equals 22 minutes.
C) 200 minutes
This option is incorrect as it greatly overestimates the time required for pizza preparation. The standard preparation time is only 20 minutes plus the allowance, not 200 minutes.
D) 20 minutes
This option is incorrect because it fails to include the 10 percent allowance that needs to be added to the normal preparation time. The standard time should reflect the additional allowance, resulting in 22 minutes.
Conclusion
The correct answer is 22 minutes, as it accurately incorporates the normal preparation time and the additional 10 percent allowance for each worker. All other options either underestimate or overestimate the time required, demonstrating a misunderstanding of the calculation involved in determining standard time.
