Tracy did a competition of 

30

 questions. Every correct answer, incorrect
answer and unanswered question was awarded 

3

 points, 

−2

 points
and 

0

 point respectively. There were 

17

 correct answers,


7

 unanswered questions, and the rest were incorrect. What was
the number of points Tracy got?

To calculate the number of points Tracy earned, we'll follow similar steps to the previous problem.

**Step 1: Identify the number of incorrect answers.**

- Total questions: 30
- Correct answers: 17
- Unanswered questions: 7
- Incorrect answers: \( 30 - 17 - 7 = 6 \)

**Step 2: Calculate the points for each type of answer.**

- Points for correct answers: \( 17 \times 3 = 51 \) points
- Points for incorrect answers: \( 6 \times (-2) = -12 \) points
- Points for unanswered questions: \( 7 \times 0 = 0 \) points

**Step 3: Calculate the total points.**

\[
\text{Total points} = 51 + (-12) + 0 = 39 \text{ points}
\]

Thus, Tracy got **39 points** in the competition.

2. If Tracy had answered all the questions, how many incorrect answers would she need to get 30 points?
3. What is the maximum score Tracy could achieve in this competition?
4. If unanswered questions were awarded 1 point each, how many points would Tracy have scored?
5. How would Tracy's score change if each incorrect answer deducted 3 points instead of 2?
