The given line graph provides data about the average monthly cost of contracts offered by four different mobile phone providers in a European country over a 9 – month period, commencing from January.
In general, all types of mobile phone providers’ monthly costs underwent fluctuation, albeit to varying degrees. Another interesting point is that Alpha showed the lowest figure at the outset, whereas it reached its peak in the last month, bucking the trend.
Looking at the details, Domo showed the highest amount at 15 euros in January, after which there was a gradual increase to 25 euros in July, which was followed by marked drop to about 24 euros in September. Meanwhile, despite the fact that Alpha witnessed the lowest figure at the beginning (5 euros), it surged and defied the trend with 25 euros in September, overtaking Domo.
Turning to Lex and Sim TX, their monthly costs gradually increased at distinct figures from January to June, beginning with about 12 and 9 euros, respectively. Notwithstanding this pattern, the two lines intersected in June, with Sim TX overtaking Lex at this point with approximately 14 euros. However, Sim TX plummeted slightly, and Lex regained the lead the following month and maintained its dominance for the remainder of the period, ultimately finishing above Sim TX in September, with respective figures of around 16 and 7 euros.
