The line graph compares four different features (domo, sim tx, lex, and alpha) in terms of their average cost of mobile phones. Units are measured in euros.
Overall, Alpha was overtaken by other mobile phones despite being the lowest in the beginning. The opposite was true for the figure for Domo. Alpha had the highest average prices, while Sim TX had the lowest at the end of the period.
In January, Domo’s initial price was about 15€, and this amount increasingly increased to approximately 23€ in July. The highest trend was for Alpha; it started at about 5€ and continued from January to June; in the following months it dramatically rose toexactly 25€ in September.
The next lowest figures, Sim TX’s cost started at about 10€ in January, and it dramatically increased to around 15€ in June, and it increasingly declined to approximately 8€ in September. Lex’s cost was about 14€ in January, but the next month it declined to 10€. And for the next 5 months, it steadily continued at 12.5€; however, it dramatically reached 19€.
