Xavier claims that the number of text messages he sends is proportional to the amount he owes on his monthly phone bill. He has listed the number of text messages sent and the amount he owed for a few months:
January: 300 text messages sent: $15.00 owed
February: 314 text messages sent; $15.70 owed
March: 486 text messages sent; $24.30 owed
April: 205 text messages sent; $10.25 owed
Which of the following methods would help Xavier prove his claim?
Xavier could divide the amount he owed in April by the number of text messages sent in April to find out how much each text message costs.
a
Xavier could create equations based on the data collected to prove that as the number of text messages increases, the amount owed also increases.
Xavier could plot data points based on the number of text messages sent in January, February, and March and the amount he owed for those months to create a
straight line on the graph.
Xavier could create a table listing the number text messages sent in each of the months listed and the name of the month to prove that equivalent ratios exist.
