Answer:
r + 17 ≤ 36
Explanation:
The inequality that represents all the possible numbers of roses that the florist can still add to the arrangement is:
r + 17 ≤ 36
This means that the total number of roses, including the 17 that have already been used, must be less than or equal to 36. The variable "r" represents the number of additional roses that the florist can add to the arrangement.
