The line graph compares the changes in revenue of four coffee shops in New York over a one-year period.
Overall, it is evident that The Tea Room experienced a sharp decline in earnings, whereas Internet Express, Wifi Cafe, and Cafe Cool all recorded upward trends throughout the year. Notably, although The Tea Room had the highest revenue for the first ten months, it was eventually overtaken by Wifi Cafe, which became the top earner by the end of the period.
Looking first at The Tea Room, its income fluctuated during the opening months, rising from about $160,000 to a peak of roughly $180,000 in March. However, from October onwards, revenue fell dramatically, dropping from $140,000 to just around $50,000 in December. In contrast, Cafe Cool showed the opposite pattern: starting at a modest $30,000 in January, its earnings increased steadily and surged to approximately $120,000 by the end of the year.
Turning to the remaining two cafes, Internet Express began the year with revenue of around $100,000, while Wifi Cafe earned only $30,000. Over time, Internet Express saw a moderate rise, finishing the year at about $140,000. Meanwhile, Wifi Cafe experienced the most remarkable growth, with its income soaring dramatically to over $190,000, making it the most profitable coffee shop in December.
