Question 1: A car depreciates 20% per year. If it costs $25,000 new, what is its value after 1 year?
- $5,000
- $15,000
- $20,000 (Correct answer)
- $22,500

- Top-left
- Bottom-left (Correct answer)
- Top-right
- Bottom-right
Correct answer: Bottom-left
90° clockwise: top-left → top-right → bottom-right → bottom-left after 3 rotations.
Question 4: If p implies q and q implies r, which must be true?
- r implies p
- p implies r (Correct answer)
- q implies p

By the transitive property of implication, p → q and q → r means p → r.
Question 5: A rectangle's length is twice its width. If the area is 72 sq units, what is the width?
- 4
- 6 (Correct answer)
- 8
- 9
Correct answer: 6
Let width = w; length = 2w; area = 2w² = 72; w² = 36; w = 6.
Question 6: Which does NOT describe a property of a parallelogram?
- Opposite sides are equal
- Opposite angles are equal
- All angles are right angles (Correct answer)
