To find the amount charged (y) based on the number of hours (x) of personal training, we can use the formula provided:

\[ y = 18 + 12x \]

Now, let's calculate the amount for each given number of hours.

  1. For 3 hours (x = 3): \[ y = 18 + 12(3) = 18 + 36 = 54 \]

  2. For 6 hours (x = 6): \[ y = 18 + 12(6) = 18 + 72 = 90 \]

  3. For 9 hours (x = 9): \[ y = 18 + 12(9) = 18 + 108 = 126 \]

Now we can complete the table:

| Hours (x) | Amount charged (y) | |-----------|---------------------| | 3 | 54 | | 6 | 90 | | 9 | 126 |

Thus:

  • For 3 hours: $54
  • For 6 hours: $90
  • For 9 hours: $126
