To analyze the scenario where Bob owes Jim $7 and earns $25 mowing the grass, we can set up the calculation as follows:
- Bob starts out with a debt of $7 (which we can represent as -$7).
- 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:
-
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.
-
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.
-
Irrational/Integer answer: Bob still owes $ in the end; 7 - 25 = -18
- This is incorrect as it uses a wrong representation of the debt.
-
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.
-
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.
