Each table can have one of the two types of bouquets available, one with a single type of flower or one with three different types of flowers. If the florist wants to make each table unique, what is the least number of types of flowers he needs?
4
5
6
7
8
Each of the 8 tables is to receive either 1 type of flower or 3 types of flower.
We can PLUG IN THE ANSWERS, which represent the least number of flower types needed.
When the correct answer choice is plugged in, at least 8 different bouquets will be possible.
Since we must determine the LEAST number of flower types needed, we should test the SMALLEST answer choice first.
Answer choice A: 4
Let the 4 types of flowers be A, B, C and D.
Bouquet options:
A
B
C
D
ABC
ABD
ACD
BCD
Total options = 8.
Success!
The correct answer is
A.
