Answer:
$12 per hour
Step-by-step explanation:
To solve how much did Robin earned per hour you just have to do a simple equation, we know that he worked 9 weeks, and that each week he worked 40 hours, so you equation would look like this:
[tex]Income=(wageperhour)*(hours worked)[/tex]
The hours worked is just a math done by multiplying the weeks worked by the hours worked per week that would be:
[tex]Hours worked=Hours worked per week*weeks\\Hours worked=(40 hours)*(9 weeks)\\Hours worked=360 hours[/tex]
So now we just put the data into our equation
[tex]Income=(wageperhour)*(hours worked)\\$4320=(wageperhour)*(360)\\wage per hour=4320/360\\ Wage per hour= 12[/tex]
