Dicks Sports has roughly _______ its sales in the past 10 years.

• A. Doubled
• B. Tripled
• C. Halved
• D. Quadrupled

Answer: (A)

Understanding growth over time means looking at how much the sales have increased compared to ten years ago, expressed as a multiplicative factor. When something has roughly doubled, it means the current sales are about two times the level from ten years earlier. That twofold increase corresponds to an approximate 100% rise over the decade.

Among the options, twofold is the right fit because it reflects a growth by a factor of about 2. A threefold increase would mean roughly tripling the original amount, a half would mean dropping to about half, and a fourfold increase would imply about four times as much. The word roughly allows a little rounding, so minor deviations around two times are still described as doubled.
