The line graph illustrates the rates of differences of the costs of three metals (copper, nickel, and Zinc) in every month in 2014. Overall, all the mentioned types of metals experienced fluctuations in their prices. Particularly, the prices of nickel sharply differed over the given period compared with copper and zinc. Unlike, the variation of rates in the copper’s prices slightly varied over the twelve-month-period.
The prices of nickel substantially fluctuated throughout the year, hitting the peak in January at 6% but ending the year with a decrease to just 1%. Sharp drops were observed from January to March, May to June, and September to October, with changes of exactly 5%, just under 4%, and 1%, respectively. There were rapid escalations in costs from June to July and from October to November, ranging from 2% to 3%. Nickel prices during the other time intervals remained relatively stable.
In contrast, copper and zinc exhibited gentler fluctuations. Zinc started the year with a 1% increase, while copper began at 2%. Zinc’s prices rose considerably in the first month, by reaching 3% while copper steadily decreased to just under 1% over the first four months. Zinc also recorded a slight decline from February to May, dropping from 3% to 1%, and a marked decline from May to June by 2%.
