Fiesta28 [93]
X = number of servers
y = number of guests

\text {number of guest per table = } 4<span>

</span>\text {number of tables = } \dfrac{y}{4}
<span>
</span>\text {number of servers needed = } \dfrac{y}{4} \div 12<span>

</span>\text {number of servers needed = } \dfrac{y}{4} \times  \dfrac{1}{12}

\text {number of servers needed = } \dfrac{y}{48}

There must be at least 1 server for every 12 tables:
x \geq \dfrac{y}{48}
