Answer:
The unit rate is $3
Explanation:
The given table can be written as follows:
No. of Bouquets 3 6 9 12
Price 9 18 27 36
In order to find the unit price, the price will be divided by the units.
So,

Taking a single pair from the table (Any pair of number of bouquets and price of those number of bouquets can be taken for this purpose)

= 3
Hence,
The unit rate is $3
