Answer:
Per Chevron 3Q 2013 Filling:
The percentage change in the cost of purchased oil products nine months to September 30, 2013 when compared to nine months in 2012 was:
2.47%
Explanation:
a) Data and Calculations:
Cost of purchased oil products:
2013 $34,822,000,000
2012 $33,982,000,000
Change $840,000,000
Percentage Change = $840/$33,982 x 100
= 2.47%
b) The implication is that Chevron's cost of purchased oil products in third quarter of 2013 increased by 2.47% when compared with the same period in 2012. This percentage change is calculated by subtracting the Q3 2012 cost of purchased oil products from the Q3 2013 cost of purchased oil products and then dividing the difference by the Q3 2012, and multiplying by 100. The change could be caused by increases in the price of oil products or other variables.
