Garrett works at the pizza shop. He gets paid $14.00 per hour if he works 8 hours or less in a day. If Garrett works more than 8 hours in a day, he receives an extra $2.00 for every hour he works over 8 hours. For example, if Garrett works 10 hours, he receives $14.00 per hour for the first 8 hours and $16.00 per hour for the last 2 hours. The piecewise function represents the amount of money Garrett will make each day if he works x hours for the day. The table provides the hours Garrett worked each day for the week. Use the table and piecewise function to determine how much he will make for the week.

To calculate Garrett's total earnings for the week based on the hours he worked each day and the piecewise function provided, we first break down his pay for each day:

  1. Monday (12 hours):

    • First 8 hours: \( 8 \times 14 = 112 \)
    • Overtime (4 hours): \( 4 \times 16 = 64 \)
    • Total for Monday: \( 112 + 64 = 176 \)

  2. Tuesday (8 hours):

    • Total: \( 8 \times 14 = 112 \)

  3. Wednesday (8 hours):

    • Total: \( 8 \times 14 = 112 \)

  4. Thursday (8 hours):

    • Total: \( 8 \times 14 = 112 \)

  5. Friday (10 hours):

    • First 8 hours: \( 8 \times 14 = 112 \)
    • Overtime (2 hours): \( 2 \times 16 = 32 \)
    • Total for Friday: \( 112 + 32 = 144 \)

Now, let's sum up the total earnings for the week:

  • Monday: \( 176 \)
  • Tuesday: \( 112 \)
  • Wednesday: \( 112 \)
  • Thursday: \( 112 \)
  • Friday: \( 144 \)

Calculating the total for the week:

\[ 176 + 112 + 112 + 112 + 144 = 656 \]

Garrett will make $656 for the week.

So, the correct response is: He will make $656.
