  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
