To find the number of magazines Jiro has read after \( x \) weeks, we can use the equation you provided:

\[ y = 5 + 5x \]

Now, we can calculate \( y \) for 3, 5, and 7 weeks.

  1. For \( x = 3 \): \[ y = 5 + 5(3) = 5 + 15 = 20 \]

  2. For \( x = 5 \): \[ y = 5 + 5(5) = 5 + 25 = 30 \]

  3. For \( x = 7 \): \[ y = 5 + 5(7) = 5 + 35 = 40 \]

Now, let's complete the table:

| Weeks (x) | Magazines (y) | |-----------|---------------| | 3 | 20 | | 5 | 30 | | 7 | 40 |

So, Jiro has read 20 magazines after 3 weeks, 30 magazines after 5 weeks, and 40 magazines after 7 weeks.
