Answer:
Step-by-step explanation:
So we have the equation:
First, note that since the sign is greater than, this is an <em>or</em> inequality (not an "and" inequality). This is the student's first mistake.
So, let's solve this inequality.
Case 1:
Subtract 1 from both sides:
Divide both sides by -4:
The student did not flip the sign when doing this step, hence the incorrect answer.
You correctly spotted the student's mistake. Nicely done!
Case 2:
This is what you're missing: for this second instance, we <em>must</em> flip the sign to <em>less than</em> right away. This is because we are essentially multiplying the 3 by a negative. So, we must flip the sign in order to be correct.
Now solve. Subtract 1 from both sides:
Divide both sides by -4. Since we're dividing by a negative, flip the sign:
So, our solutions are:
As mentioned previously, this is an <em>or</em> inequality. Therefore, our final answer is:

Explanation
The income is $42,000
