Abigail, a florist, is assembling bouquets of roses to sell at her flower shop. The number of bouquets she can assemble depends on how many roses are in her shop.

b = the number of bouquets Abigail can assemble
r = the number of roses in the flower shop

Which of the variables is independent and which is dependent?

The independent variable is the number of roses in the flower shop (r), as it is the factor that Abigail can control and manipulate. The dependent variable is the number of bouquets Abigail can assemble (b), as it depends on the number of roses available.
