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

For questions 1 – 2, use the following scenario to identify the equation described.

Two different telephone carriers offer the following plans that a person is considering. Company A has a monthly fee of $20 and charges $0.05/minute for calls. Company B has a monthly fee of $5 and charges $0.10/minute for calls.
  1. Find the model for the entire  cost, c ,  when Company A’s plan is used for m minutes.
  1. c = 5 + 0.05 m
  2. c = 20 + 0.10 m
  3. c = 5 + 0.10 m
  4. c = 20 + 0.05 m
  1. Find the model for the entire cost, c , when  Company B’s plan is used for m minutes.
  1. c = 5 + 0.05 m
  2. c = 20 + 0.10 m
  3. c = 5 + 0.10 m
  4. c = 20 + 0.05 m
  1. If a carpenter sawed a 10-ft board into two sections and one section was n ft long, how long would the other section, S , be in terms of n ?
  1. S = 10 2 n
  2. S = 10 − 2 n
  3. S = 10 − n
  4. S = 10 n
