The line graph illustrates the prices of four types of bread – wholegrain, brown, white, and rye – between 2001 and 2005.
Overall, it is clear that brown and white bread showed an upward trend over the period, while wholegrain bread experienced significant fluctuations. Rye bread remained the cheapest throughout with only slight changes.
In 2001, prices for all types of bread were relatively low and similar, at around $0.6, except for wholegrain bread, which was slightly higher at approximately $0.8. In the following year, there was a sharp rise in prices, particularly for wholegrain bread, which peaked at about $1.8, the highest point on the chart. Brown bread also increased significantly to around $1.5, while white bread rose to about $1.0. In contrast, rye bread fell slightly to roughly $0.5.
From 2003 onwards, wholegrain bread dropped considerably, falling to around $1.1 in 2003 and reaching a low of approximately $0.7 in 2004 before recovering slightly in 2005. Brown bread, however, continued to rise overall despite a small dip in 2004, ending at about $1.6 in 2005. White bread showed a steady increase throughout the period, finishing at approximately $1.3. Rye bread remained relatively stable, fluctuating slightly between $0.5 and $0.7.
In conclusion, brown and white bread became more expensive over time, while wholegrain bread showed volatility and rye bread stayed the least expensive.
