Final answer:
The inequality representing the maximum number of sunflower plants 's' and lily plants 'l' that Ezra can water with a limit of 11 liters is 0.7s + 0.4l ≤ 11.
Step-by-step explanation:
The student is asking to write an inequality that represents the number of sunflower plants s and the number of lily plants l that Ezra can water every day, given a limit of 11 liters of water.
As every sunflower plant requires 0.7 liters and every lily plant requires 0.4 liters, the inequality to represent this situation can be written as:
0.7s + 0.4l ≤ 11
This inequality indicates that the total amount of water used to water the sunflower plants and lily plants together should not exceed 11 liters.
