Final answer:
To calculate the monthly salary for Morgan's employees at the stadium, we need to multiply the number of hours worked by each category of employee with their respective hourly wages and sum the total for each category.
Step-by-step explanation:
To calculate the monthly salary for Morgan's employees, we must first understand that each category of employee has a different hourly wage. Ticket sellers are paid per Silhout, cleaning persons earn $10 per hour, and ushers are compensated at $12 per hour. Assuming 'Silhout' is a typographical error and should represent an hourly wage, let's denote this as 'S' for the purpose of calculation. To proceed, we will need to know the exact hourly wage for ticket sellers to give an accurate calculation.
Since the provided hourly rates and monthly hours worked are given, the monthly salary for each group of employees would be calculated as follows (assuming 'Silhout' is replaced with a numerical value 'S'):
Ticket Sellers: 10 * S * 50
Cleaning Personnel: 15 * $10 * 50
Ushers: 12 * $12 * 50
By summing up these amounts, we can obtain the total monthly salary that Morgan will need to pay her staff, assuming they all work for the average 50 hours per month.
For example, if 'Silhout' was $10, we could calculate it as:
Ticket Sellers: 10 * $10 * 50 = $5,000
Cleaning Personnel: 15 * $10 * 50 = $7,500
Ushers: 12 * $12 * 50 = $7,200
The total monthly salary would then be $5,000 (Ticket Sellers) + $7,500 (Cleaning Personnel) + $7,200 (Ushers) = $19,700.
