54. A restaurant's best-selling dish is its signature pizza. To bring this pizza to the customer's 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 calculate the standard time for preparing the signature pizza, we need to account for the 10 percent allowance added to the normal time of 20 minutes. This results in a total of 22 minutes.
A) 20 minutes
This option represents only the normal time required for preparing the pizza and does not include the worker's allowance. Therefore, it is not the correct standard time.
B) 22 minutes
This option correctly takes into account the 10 percent allowance for each worker. The standard time is calculated by adding 10 percent of 20 minutes (which is 2 minutes) to the normal time, resulting in a total of 22 minutes.
C) 200 minutes
This option is excessively long and does not relate to the normal time needed to prepare the pizza. It overestimates the time significantly, making it incorrect.
D) 2 minutes
This option is far too short to represent the time required for preparing the pizza. It disregards the actual preparation time and the allowance, rendering it incorrect.
Conclusion
The correct answer of 22 minutes effectively incorporates the necessary 10 percent allowance for workers, aligning with the restaurant's operational standards. All other options fail to consider this allowance or miscalculate the necessary time, demonstrating a lack of understanding of the standard time calculation process.
