  1. A store sells a jacket for $85.00 after applying a 15% discount. What was the original price?

    Answer: $100.00

    If $85 is 85% of the original price, then the original price = $85 ÷ 0.85 = $100.00.

  2. What is the value of 3² + 4² ?

    Answer: 25

    3² = 9 and 4² = 16; 9 + 16 = 25.

  3. Simplify: 5(2x − 3) + 4x

    Answer: 14x − 15

    Distribute: 10x − 15 + 4x = 14x − 15.

  4. A recipe calls for 2¾ cups of flour. If you want to make 1½ times the recipe, how many cups of flour do you need?

    Answer: 4 1/8 cups

    2¾ × 1½ = 11/4 × 3/2 = 33/8 = 4 1/8 cups.

  5. A car travels 240 miles using 8 gallons of gas. At the same rate, how many gallons are needed to travel 360 miles?

    Answer: 12 gallons

    Rate = 240/8 = 30 mpg. Gallons needed = 360 ÷ 30 = 12 gallons.

  6. What is the median of the following set of numbers: 7, 12, 3, 9, 5, 15, 8?

    Answer: 8

    Arranged in order: 3, 5, 7, 8, 9, 12, 15. The middle value (4th of 7) is 8.
