Workers at a factory produce a toy with a defect about once every 4 hours on average. each toy costs the factory approximately $7 in labor and supplies.

c) what is the expected cost to the factory for toys with defects at the end of a 40-hour work week?

$70 is the expected cost.  

Step-by-step explanation:

A toy with a defect is produced once every 4 hours on average. To calculate the total of toys with a defect at the end of a 40-hour work week, you must follow the next steps:

1. Divide the total of hours of the work week by the time average of a toy with a defect is produced in the factory:

This means 10 toys with a defect are produced on average in a 40-hour work week.  

2. Now that you calculated the number of toys with a defect, multiply it by the cost to the factory to produce one defected toy which is 7$:

To conclude, $70 is the expected cost to the factory for toys with defects at the end of a 40-hour work week, having in mind that the factory produces a toy with a defect about once every 4 hours on average.
