Advanced Algebra II Notes 3.6 Linear Systems Example A: Minh and Daniel need to decide between two long-distance carriers. One company offers the Phrequent Phoner Plan, which costs 20 cents for the first minute of a phone call and 17 cents for each minute after that. The Small Business Plan costs 50 cents for the first minute and 11 cents for each additional minute. Which plan should Minh and Daniel choose? Solve algebraically: Solve by graphing:

Example B: Justine and her little brother Evan are running a race. Because Evan is younger, Justine gives him a 50-foot head start. Evan runs at 12.5 feet per second and Justine runs at 14.3 feet per second. How far will they be from Justine’s starting line before Justine passes Evan? What distance should Justine mark for a close race? Solve algebraically: Solve by graphing:
