Transcript text: Use the line graph to the right to answer the following question. For which 10 -year time period was the increase in supply of motor gasoline the greatest?
Petroleum products supplied by type in one region
Solution
Solution Steps
Step 1: Identify the data points for motor gasoline
1960: 4.07 million barrels per day
1970: 4.81 million barrels per day
1980: 5.64 million barrels per day
1990: 6.62 million barrels per day
2000: 8.22 million barrels per day
Step 2: Calculate the increase for each 10-year period
1960 to 1970: 4.81 - 4.07 = 0.74 million barrels per day
1970 to 1980: 5.64 - 4.81 = 0.83 million barrels per day
1980 to 1990: 6.62 - 5.64 = 0.98 million barrels per day
1990 to 2000: 8.22 - 6.62 = 1.60 million barrels per day
Step 3: Determine the greatest increase
The greatest increase is from 1990 to 2000 with an increase of 1.60 million barrels per day.
Final Answer
The increase in supply of motor gasoline was the greatest during the period from 1990 to 2000.
