Answer:

\frac{3}{4}a\leq 15

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}

Given,

Joey attends 15 of the activities to remains on the student council,

Also, his activity must be greater than \frac{3a}{4}.

\implies \frac{3}{4}a\leq 15

Which is the required inequality.
