To analyze the given amounts borrowed and the corresponding amounts repaid, we can express the relationship between the amounts borrowed (x) and the amounts repaid (y) as a linear equation.

From the provided data:

  • When $100 is borrowed, $120 is repaid.
  • When $200 is borrowed, $240 is repaid.
  • When $500 is borrowed, $600 is repaid.
  • When $800 is borrowed, $960 is repaid.

We can see that the amount repaid (y) is proportional to the amount borrowed (x).

Let’s calculate the ratio for some of the pairs:

  1. For $100 borrowed: \[ \frac{120}{100} = 1.2 \]

  2. For $200 borrowed: \[ \frac{240}{200} = 1.2 \]

  3. For $500 borrowed: \[ \frac{600}{500} = 1.2 \]

  4. For $800 borrowed: \[ \frac{960}{800} = 1.2 \]

This indicates that the amount repaid (y) is 1.2 times the amount borrowed (x).

We can represent this relationship as: \[ y = 1.2x \]

Now, let's rewrite this relationship in a different form: To express 1.2 as a fraction, we can write: \[ 1.2 = \frac{12}{10} = \frac{6}{5} \] Thus, we have: \[ y = \frac{6}{5}x \]

Let's check the options presented in terms of y:

  1. \(y = 65x + 10\) - Incorrect.
  2. \(y\) is equal to \(6/5x + 10\) - Incorrect.
  3. \(y = 56x + 10\) - Incorrect.
  4. \(y\) is equal to \(5/6x + 10\) - Incorrect.
  5. \(y = 56x\) - Incorrect.
  6. \(y\) is equal to \(5/6y\) - Incorrect.
  7. \(y\) is equal to \(6/5x\) - Correct.

Hence, the correct response in the context of the mathematical relationship derived from the data provided is: y = 6/5x (Option that represents the relationship of repaid to borrowed).
