The line graph reveals the information about how many dollars four cafes in New York had earned after 12 months in a year.
Overall, it is clear that there were two basic trends: upward and downward. Only the earnings of The Tea Room fell dramatically, while that of the others rose constantly over the period.
Specifically, in terms of The Tea Room, after going ups and downs wildly from $160 to $120 in the first 8 months, its income declined sharply to under $50 at the end of the year.
By contrast, the others’ income increased by varying degrees. For instance, the first 6 months saw an insignificant drop in the earnings of Internet Express from $100 to $80, followed by a gradual rise from $80 to over $120 in the other half of the year. Moreover, both Wifi Cafe and Cafe Cool ended the year up in December. Between January and July, the former’s income doubled from $50 to $100 and then fell considerably to $60 in the next two months, before rocketing to over $180 in December. Likewise, although Cafe Cool’s earnings experienced a wild fluctuation from $30 to nearly $60 in the first 10 months, it climbed rapidly to $120 in the last months.
