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?

If 12 types only last 4 days, and the rest last an average of 6, then the average amount of days that ALL the flowers wilt would be 5. To find the average, you add 6 and 4 to get 10, and since there is only 2 number we added togehter to get 10, you would divide 10 by 2 to get 5!
