Answer 1

To calculate the total earnings for the grocery store employee who works 55 hours in a week, we break it down into two parts:

1. Regular hours (up to 40 hours):

   • The employee earns $15 per hour for the first 40 hours.
   • Earnings for 40 hours: \( 40 , \text{hours} \times 15 , \text{$} = 600 , \text{$}\)

2. Overtime hours (hours beyond 40):

   • The employee works 55 hours in total, which means he worked \( 55 - 40 = 15 , \text{hours}\) of overtime.
   • The overtime pay is $20 per hour.
   • Earnings for 15 hours of overtime: \( 15 , \text{hours} \times 20 , \text{$} = 300 , \text{$}\)

3. Total earnings for the week:

   • Total earnings = Earnings for regular hours + Earnings for overtime hours
   • Total earnings = \( 600 , \text{$} + 300 , \text{$} = 900 , \text{$}\)

Therefore, if the employee works 55 hours in the week, he will make $900.

So, the correct response is: $900
