The line graph illustrates the monthly sales figures of Istanbul Promo Plus in 2007, measured in millions of Turkish lira.
Overall, sales fluctuated considerably throughout the year. The highest point was recorded in March, while the lowest figure occurred in July. Although sales declined in the middle of the year, they showed signs of recovery towards the end of the period.
In January, sales stood at about 200 million lira and increased slightly to around 220 million in February. This upward trend continued sharply in March, when revenue peaked at approximately 350 million lira. However, sales then dropped significantly to about 250 million in April and continued to fall in May and June, reaching roughly 200 million and 150 million respectively. The lowest level was seen in July at around 120 million lira.
After July, sales rebounded to approximately 210 million in August before declining again to nearly 120 million in September. From October onwards, the figures gradually rose, ending the year at around 190 million lira in December. This suggests a partial recovery in the final months, though sales never returned to the March peak.
