Answer:
Number line with open circle on 4 and shading to the right.

Explanation:

Call x the number of students that need to sign up so that more than one van is neeed to transport them =>
 
x + 3 > 7

=> x > 7 - 3

=> x > 4

That is the numbers greater than 4, withount including the number 4.

That in the number line is the set of numbers to the right of 4, and the open circle is used to indicate that the number 4 is not included (a closed circle would indicate that the number 4 is included, which is not the case).
