Let's solve the problem step-by-step.
1. Jack won 65 lollipops.
2. He gave 4 lollipops to each student in his math class.
3. He has 1 lollipop remaining.
We can set up the equation to find the number of students in the class:
Let \( x \) be the number of students in Jack's math class.
The total number of lollipops given away is \( 4x \) (since he gives 4 lollipops to each student).
According to the information given, the total number of lollipops he had can be described as:
Initial lollipops - Lollipops given = Remaining lollipops
So we can write:
\[ 65 - 4x = 1 \]
Now, let's solve for \( x \):
1. First, subtract 1 from both sides:
\[ 65 - 1 = 4x \]
\[ 64 = 4x \]
2. Now, divide both sides by 4:
\[ x = \frac{64}{4} \]
\[ x = 16 \]
Thus, the number of students in his math class is **16**.
Therefore, the correct answer is **16**.
