Answer:
8 coasters per hr
Step-by-step explanation:
To find Herman's rate of selling coasters, you need to divide the total number of coasters sold by the total number of hours worked.
Herman worked for 7 days (including weekends) in the last week, so he worked a total of \(7 \text{ days} \times 9 \text{ hours/day} = 63 \text{ hours}\).
Now, the rate of selling coasters per hour would be:
\[ \text{Rate of selling coasters} = \frac{\text{Total number of coasters sold}}{\text{Total number of hours worked}} \]
\[ \text{Rate of selling coasters} = \frac{504 \text{ coasters}}{63 \text{ hours}} \]
\[ \text{Rate of selling coasters} = \frac{504}{63} \text{ coasters/hour} \]
\[ \text{Rate of selling coasters} = 8 \text{ coasters/hour} \]
So, Herman sold coasters at a rate of 8 coasters per hour.
