Answer:
![\frac{3}{4}a\leq 15](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Da%5Cleq%2015)
Step-by-step explanation:
Here, a be the total amount of student council activities,
Since, a student must attend at least 3/4 of the activities,
Thus, the least number number of activities a student must attend = 3/4 of a
![=\frac{3a}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3a%7D%7B4%7D)
Given,
Joey attends 15 of the activities to remains on the student council,
Also, his activity must be greater than
.
![\implies \frac{3}{4}a\leq 15](https://tex.z-dn.net/?f=%5Cimplies%20%5Cfrac%7B3%7D%7B4%7Da%5Cleq%2015)
Which is the required inequality.
