Complete the following questions to practice the skills you have learned in this lesson.

For questions 1 – 5, use the following scenario to identify the expression, equation, or inequality described.

To support a local senior citizens center, a student club sent a flier home to the n students in the school. The flier said, “Please bring in money to support the senior citizens center. Paper money and coins accepted!” Their goal is to raise T dollars.

Choose the expression, equation, or inequality, from the list, that describes the given quantity.

  1. The dollar amount the club would have if they reached half of their goal.
  1. T − 0.5 n
  2. 0.5 n
  3. 0.25 n
  4. 0.5 T
  5. T + 50
  1. The dollar amount the club would have if every student at the school donated 50 cents to the cause.
  1. T − 0.5 n
  2. 0.5 n
  3. 0.25 n
  4. 0.5 T
  5. T + 50
  1. The dollar amount the club could donate if they made $50 more than their goal.
  1. T − 0.5 n
  2. 0.5 n
  3. 0.25 n
  4. 0.5 T
  5. T + 50
  1. The dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents.
  1. T − 0.5 n
  2. 0.5 n
  3. 0.25 n
  4. 0.5 T
  5. T + 50
  1. The dollar amount the club would have if half of the students at the school each gave 50 cents.
  1. T − 0.5 n
  2. 0.5 n
  3. 0.25 n
  4. 0.5 T
  5. T + 50
  1. Each of the 10 students in the baking club made 2 chocolate cakes for a fundraiser. They all used the same recipe, using c cups of flour in total.
