The chart illustrates the fare of 800 grams of four different kinds of bread in the USA started from 2015 untill 2035. The significant difference of the fee from 2015 to 2035 is the Wholegrain bread that had a sharp fall in 2025 and the second one is Brown that had a steady growth and stayed a leader from 2025 to 2035.
Even though three from four types of bread had started with the price of 0.6 dollars, Brown had a fast growth from 2015 to 2020 and then steadily grew with some fluctuations, but still stayed as a leader with the final price 1.6 dollars. White had a steady growth from the start to the end and became 1.3 dolllars in the end.
Rye had some fluctiuations during all the time but remained as the least and last with about 0.5 dollars. Wholegrain was the one with the highest price for 5 years, but after challenged a sharp fall that continued untill the 2035 and became one of the last with 0.8 dollars.
In conclusion, Wholegrain and Brown had the most noticable changes in 20 years.
