Question

There are 16 types of flowers used to decorate for a party. Twelve of the flowers types last an average of 4 days before they wilt. The remaining flowers last an average of 6 days.
What is the average number of days before the flowers wilt?

Answer 1

Answer: The average number of days before the flowers wilt is 5 days .

Step-by-step explanation:

Since we have given that

Total number of flowers used to decorate for a party = 16

Number of days 12 of the flowers types last = 4 days

Number of days 4 of the flowers types last = 6 days

Since there are only 2 types of flowers that were group into.

We need to find the average number of days before the flowers wilt is given by

$=\frac{4+6}{2}\\\\=\frac{10}{2}\\\\=5$

Hence, the average number of days before the flowers wilt is 5 days .

Answer 2

16 - 12 = 4 flowers
4f = 6 days
1 flower = 1.5 days

1.5 × 16 = 24 days
