  1. A store sells a jacket for $85. During a sale, the price is reduced by 20%. What is the sale price?

    Answer: $68.00

    20% of $85 is $17, so the sale price is $85 − $17 = $68.

  2. If 5x − 3 = 22, what is the value of x?

    Answer: 5

    Add 3 to both sides to get 5x = 25, then divide by 5 to get x = 5.

  3. A car travels 240 miles in 4 hours. At the same speed, how long will it take to travel 300 miles?

    Answer: 5 hours

    The speed is 60 mph, so 300 ÷ 60 = 5 hours.

  4. What is the value of 3² + 4²?

    Answer: 25

    3² = 9 and 4² = 16, and 9 + 16 = 25.

  5. A recipe calls for 2¼ cups of flour. If you want to make 1½ times the recipe, how many cups of flour do you need?

    Answer: 3⅜ cups

    2¼ × 1½ = 9/4 × 3/2 = 27/8 = 3⅜ cups.

  6. Which of the following is closest to √50?

    Answer: 7

    Since 7² = 49 and 8² = 64, √50 is closest to 7.

  7. A worker earns $12.50 per hour and works 38 hours in a week. What are her total weekly earnings?

    Answer: $475.00

    $12.50 × 38 = $475.00.
