What is the average hourly wage across all your workers?
To solve:
Add up the total cost of each of the 10 workers: cashiers $10x5=$50, stockers $9x2=$18, salespeople $14x3=$42. Add up the total cost which is $110. To find the average hourly wage divide the total cost $110 by 10 employees = $11.
$11 is the average hourly wage across all of your workers.
