The line graph illustrates the average cost of monthly contracts of four different cellular companies, Domo, Lex, SIM TX, and Alpha, in a European country from January to September 2012, measured in euros.
Overall, Domo usually had the highest charges throughout most of the period, while Alpha started with the lower fees but increased towards the end, with CMTX which peaked in the middle of the year, and Lex demonstrated a gradual increase.
Focusing on increase first, Domo’s contract made up around €15, rose gradually to reach a peak of €25 in July before declining to about €23 in September. Lex started at about €12 in January, declined in the next months, and then rose steeply to approximately €19 in September. CMTX began at €8 and increased significantly, peaking at €14 in June, but declined to around €7 by September. By contrast, Alpha started with €5 and decreased considerably until July, after which it sharply grew to €25 in September.
In conclusion, while Domo kept the highest cost for most months and SIM TX experienced a mid-year peak, Alpha’s growth in the last two months made it the most expensive provider by September, and Lex showed a consistently upward trend. оцени
