Final answer:
The piece rate for assembly line workers who are expected to assemble 20 toys per hour would be $0.75 per toy, calculated by dividing the standard hourly wage of $15.00 by the expected output.
Step-by-step explanation:
When determining the piece rate to pay assembly line workers, we consider the standard hourly wage of $15.00 and the expected output of 20 toys per hour. The piece rate is calculated by dividing the hourly wage by the number of toys an employee is expected to assemble per hour.
To find the piece rate per toy, we divide $15.00 by 20, resulting in $0.75 per toy. Therefore, for each toy assembled, a worker would earn $0.75. This aligns with the aim of compensating workers based on their output, ensuring that they are paid fairly for their productivity.
