A bouquet initially contains 6 flowers on average. If the seller doubles the flowers in each bouquet, what is the new average number of flowers per bouquet?

Difficulty: Easy

Correct Answer: 12

Explanation:

Introduction / Context:Uniform scaling of every data point scales the average by the same factor. Doubling every bouquet's count doubles the mean as well.

Given Data / Assumptions:

  • Original average flowers per bouquet = 6
  • Each bouquet is doubled

Concept / Approach:If each value is multiplied by k, the average is multiplied by k. Here k = 2.

Step-by-Step Solution:

Original average = 6 Scaling factor = 2 New average = 6 * 2 = 12

Verification / Alternative check:Consider three bouquets with counts 5, 6, 7 (average 6). Doubling gives 10, 12, 14 (average 12). Pattern generalizes to any data set.

Why Other Options Are Wrong:

  • 3: This would be halving, not doubling.
  • 8: Not consistent with a full factor-of-two increase.
  • none of these and 6: Both ignore the uniform scaling rule.

Common Pitfalls:Confusing doubling with adding a fixed number; multiplying is required here.

Final Answer:12
