Answer: Stella would earn $184 in 23 hours.
Step-by-step explanation: First we need to find the unit rate so start by dividing by 9
[tex]\frac{72}{9} =8\\\frac{9}{9}=1[/tex]
Now we know every hour Stella will earn $8. We can now multiply the amount for 1 hour by 23 to get the amount for 23 hours.
8x23=184
1*23=23
Now we can see that Stella would earn $184 for working 23 hours.
