  1. A school fundraiser sells cookies for $2 each and brownies for $3 each. If Theo bought only brownies and spent $21, how many brownies did he buy?

    Answer: 7

    3b = 21 → b = 7.

  2. Solve for t: 4(t + 2) − 3(t − 1) = 15

    Answer: 4

    4t + 8 − 3t + 3 = 15 → t + 11 = 15 → t = 4.

  3. If 3x − 2 = 13, what is the value of 9x − 6?

    Answer: 39

    9x − 6 = 3(3x − 2) = 3(13) = 39.

  4. A road trip covers 420 miles. Ivan has driven x miles and still has 3 times that distance remaining. How many miles has Ivan driven?

    Answer: 105

    x + 3x = 420 → 4x = 420 → x = 105.

  5. Solve for y: 0.4y + 2.6 = 5.4

    Answer: 7

    0.4y = 5.4 − 2.6 = 2.8 → y = 7.

  6. In the equation 3(2x − p) = 24, if x = 5, what is the value of p?

    Answer: 2

    3(10 − p) = 24 → 10 − p = 8 → p = 2.

  7. An internet plan charges a flat monthly fee of $35 plus $5 for every GB over 10 GB. Selena's bill was $60. How many GB over the base limit did she use?

    Answer: 5

    5g + 35 = 60 → 5g = 25 → g = 5.
