China = 4 * Brazil
To solve this problem, let's define a variable.
Let's say,
C = the amount of energy consumed by China in one year in this case.
Now, given that China consumed 4 times as much energy as Brazil, we can write an expression to represent the amount of energy China used that year.
The amount of energy consumed by Brazil can be represented as B.
Since China consumed 4 times as much energy as Brazil, we can express this relationship as:
C = 4B
Therefore, the expression for the amount of energy China used that year is 4B.
