The line graph shows the price fluctuations of four different types of bread – wholegrain bread, brown bread, white bread, and rye bread – calculated per 800-gram serving in a European country from 2001 to 2005.
Overall, the prices of brown bread and white bread tended to increase significantly, while wholegrain bread experienced considerable volatility.
Conversely, rye bread remained the most affordable option, maintaining relatively stable prices throughout this period. Specifically, brown bread had a starting price of 0.6 euros in 2001, similar to white bread and rye bread. However, its price surged to 1.5 euros in 2002 and continued to rise, eventually becoming the most expensive bread at 1.6 euros in 2005. Similarly, white bread also experienced a steady and consistent price increase, more than doubling from its initial price, reaching 1.3 euros by the end of the period. Whole wheat bread, on the other hand, showed a different trend. After an initial sharp price increase from 0.8 euros to a peak of 1.8 euros in 2002, its price plummeted to 0.7 euros in 2004. It then recovered slightly to 0.8 euros in 2005. Meanwhile, rye bread remained the cheapest bread throughout this period; although slightly reduced in 2002, its price stabilized between 0.6 and 0.7 euros.
