Student ratio is $7 : 4 \mathmr{and} 7 C$ to $4 N$

If $C = 28$, then $N = 16$, so total students $= 44$

#### Explanation:

We know the student ratio was $7 : 4$ for those who went to college $C$ and those who did not $N$.

So for every $7 C$ there are $4 N$. And $28$ went to college.

For this year: $7 C = 28$, so the multiplier for $C$ is $\frac{28}{7} = 4$.

Because of the ratio, that means the multiplier for $N$ is also $4$.

Then $4 N = 4 \times 4 = 16$, so 16 students did not go to college.

Graduating class was then $28 + 16 = 44$ students.
