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

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

1 answer

Let's analyze Bob's financial situation step by step:

  1. Bob owes Jim $7. This is a negative amount for Bob, so we can represent this as -$7.
  2. Bob earns $25 mowing the grass. This is a positive amount for Bob, represented as +$25.

So, we need to calculate Bob's overall financial position by combining these two amounts:

\[ -7 + 25 \]

Now, let's calculate that:

\[ -7 + 25 = 18 \]

This shows that Bob will have $18 left after paying off his debt to Jim.

Now, let's review the responses provided:

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

    • Incorrect (he has $18).
  2. Rational/Integer answer: Bob has some $ in his pocket in the end: -7 + 25 = 18.

    • Correct (this correctly describes his situation).
  3. Irrational answer: Bob still owes $ in the end: -7 - 25 = -32.

    • Incorrect (wrong math and scenario interpretation).
  4. Rational answer: Bob has some $ in his pocket in the end: 7 - 25 = -18.

    • Incorrect (wrong math).
  5. Irrational/Integer answer: Bob still owes $ in the end; 7 - 25 = -18.

    • Incorrect (wrong math and situation interpretation).

Based on this analysis, the correct response is:

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