Irrational answer: Bob still owes $ in the end: -7 - 25 = - 32
Irrational answer: Bob still owes $ in the end: -7 - 25 = - 32

Rational answer: Bob has some $ in his pocket in the end: 7 - 25 = -18
Rational answer: Bob has some $ in his pocket in the end: 7 - 25 = -18

Irrational/Integer answer: Bob still owes $ in the end; 7 - 25 = - 18
Irrational/Integer answer: Bob still owes $ in the end; 7 - 25 = - 18

Whole number answer: Bob breaks even and does not owe $ or have any $ in his pocket.
Whole number answer: Bob breaks even and does not owe $ or have any $ in his pocket.

Rational/Integer answer: Bob has some $ in his pocket in the end: -7 + 25 = 18

To analyze the scenario where Bob owes Jim $7 and earns $25 mowing the grass, we can set up the calculation as follows:

  1. Bob starts out with a debt of $7 (which we can represent as -$7).
  2. Bob earns $25.

To find out how much money Bob has after paying off his debt, we can use the equation:

\[ -7 + 25 \]

Calculating this gives us:

\[ -7 + 25 = 18 \]

This means that after paying off his $7 debt, Bob has $18 in his pocket.

Now, let's evaluate the responses:

  1. Irrational answer: Bob still owes $ in the end: -7 - 25 = -32

    • This is incorrect because it misrepresents the scenario and leads to an irrelevant calculation.
  2. Rational answer: Bob has some $ in his pocket in the end: 7 - 25 = -18

    • This is incorrect because it doesn't consider the debt properly.
  3. Irrational/Integer answer: Bob still owes $ in the end; 7 - 25 = -18

    • This is incorrect as it uses a wrong representation of the debt.
  4. Whole number answer: Bob breaks even and does not owe $ or have any $ in his pocket.

    • This is incorrect as well; Bob does not break even; he gains money.
  5. Rational/Integer answer: Bob has some $ in his pocket in the end: -7 + 25 = 18

    • This answer is correct. It reflects Bob's actual financial state after earning $25 and paying off his $7 debt.

Thus, the correct response is:

Rational/Integer answer: Bob has some $ in his pocket in the end: -7 + 25 = 18.
