Donald had 14 correct answers and 7 unanswered questions in a
test of 40 questions. The rest of the questions were incorrect.
Given that every correct answer, incorrect answer and unanswered
question is awarded 4 points, −2 points and 0 point respectively,
find the number of points Donald got.

To determine the number of points Donald received, we can follow these steps:

1. **Identify the given information**:
   - Total number of questions: 40
   - Correct answers: 14
   - Unanswered questions: 7
   - Points for each correct answer: 4 points
   - Points for each incorrect answer: -2 points
   - Points for each unanswered question: 0 points

2. **Determine the number of incorrect answers**:
   \[
   \text{Incorrect answers} = \text{Total questions} - (\text{Correct answers} + \text{Unanswered questions}) = 40 - (14 + 7) = 40 - 21 = 19
   \]

3. **Calculate the total points**:
   - Points from correct answers: \(14 \times 4 = 56\) points
   - Points from incorrect answers: \(19 \times -2 = -38\) points
   - Points from unanswered questions: \(7 \times 0 = 0\) points

4. **Add up all the points**:
   \[
   \text{Total points} = 56 + (-38) + 0 = 56 - 38 = 18 \text{ points}
   \]

So, Donald got **18 points**.

Here are 5 related questions:
1. How would the total score change if the unanswered questions were worth -1 point instead of 0?
2. If Donald had answered 5 more questions correctly, what would his new total score be?
3. What would Donald's score be if he answered all questions correctly?
4. How many more correct answers would Donald need to double his current score?
5. If the penalty for incorrect answers was increased to -3 points, how would this affect his score?

**Tip:** When solving problems like this, always ensure that you carefully consider each type of question (correct, incorrect, unanswered) and apply the appropriate points before summing them up.
