After researching online, you discover that AT&T offers more plan options. However, you want to compare Verizon Wireless Plan minutes to AT&T minutes. • On one coordinate graph, plot the charges for each plan per minute on the AT&T network. • AT&T Plans: • 500 minutes for $60 • 1000 minutes for $80 • 1250 minutes for $100 • 1750 minutes for $120 • 2000 minutes for $170 • 2500 minutes for $220 • On a second coordinate graph, plot the charges for each plan per minute on the Verizon Wireless network when comparing the same amount of minutesto AT&T. • Verizon Wireless Plans: • 450 minutes $40 with $.20 per minute overage; How much is 500 minutes? • 900 minutes $60 with $.15 per minute overage; How much is 1000 minutes? How much is 1250 minutes? • 1500 minutes $130 with $.10 per minute overage; How much is 1750 minutes? How much is 2000 minutes? • Unlimited minutes (2250 minutes and up) $175; How much is 2500 minutes? • On a third coordinate graph, plot the charges for both plans per minute comparing the same amount of minutes as AT&T. • Why, if at all does it make sense to connect the dots on your plots? • Which plan is the best for the following minutes: • 500 minutes- • 1000 minutes- • 1250 minutes- • 1750 minutes- • 2000 minutes- • 2500 minutes- • Based on your personal usage, which plan is best for you and why?
