$23.25 per hour
work 40 hours per week
Find your annual Salary
In a month, there are approximately 4 or 5 weeks (only refer to regular working days)
Let’s only use 4.
=> 40 x 4
=>160 hours in 1 month
In a years there are 12months
=> 12 x 4
=> 48 weeks in a years (only for regular working days) or let’s round it to 50 weeks per year
Now, let’s multiply 48 weeks by 40 hours and 50 by 40 hours
=> 48 x 40
=> 1920 hours in a year
=> 50 x 40
=> 2000 hours
Now, let’s find how much is your annual salary
=> 1920 x 23.25 = $44 640
=> 2000 x 23.25 =$46500
=>approximate or around

If a student earns $23.25 per hour and works 40 hours each week, their annual salary would be approximately $48,360, assuming they work 52 weeks a year without any breaks. This is calculated by first determining weekly earnings and then multiplying by the number of weeks in a year.
