Set up a Population chart, letting X denote the number of users one year ago:
12 months ago=x
8 months =2x
4...=4x
NOW=8x
Ten times the number of users one year ago is 10X, while the number of users today is 8X.
Therefore, 10X is greater than 8X because X must be a positive number. Thus, Quantity A is greater.
12 months ago=x
8 months =2x
4...=4x
NOW=8x
Ten times the number of users one year ago is 10X, while the number of users today is 8X.
Therefore, 10X is greater than 8X because X must be a positive number. Thus, Quantity A is greater.
