  1. A store offers a 20% discount on a $50 jacket. What is the sale price?

    Answer: $40

    20% of $50 is $10, so the sale price is $50 − $10 = $40.

  2. Which of the following is a prime number?

    Answer: 29

    29 has no factors other than 1 and itself, making it prime.

  3. Solve for x: 2x − 5 = 11.

    Answer: 8

    Add 5 to both sides to get 2x = 16, then divide by 2 to get x = 8.

  4. What is the mean of the data set 4, 8, 6, 10, 12?

    Answer: 8

    The sum is 40 and there are 5 values, so 40 ÷ 5 = 8.

  5. A triangle has angles of 50° and 60°. What is the measure of the third angle?

    Answer: 70°

    The angles of a triangle sum to 180°, so 180 − 50 − 60 = 70°.

  6. Which value of x makes the inequality x + 4 > 9 true?

    Answer: 6

    x must be greater than 5, and 6 is the only choice that satisfies this.

  7. What is the volume of a cube with edge length 3 inches?

    Answer: 27 cubic inches

    Volume of a cube is edge cubed, so 3 × 3 × 3 = 27 cubic inches.
