3. Volunteer drivers are needed to bring 30 students to the championship baseball game. Drivers either have cars, which can seat 3 students, or vans,
which can seat 5 students. The equation 3c+5v=30 describes the relationship
between the number of cars, c, and number of vans, v, that can transport exactly
30 students. Select all statements that are true about the situation.
There's multiple answers. You must choose all of the correct answers to get this one right.
If 5 cars go, then 3 vans are needed.
8 cars and 1 van isn't enough space to transport all the students
c=3 and v=4 are a pair of solutions to the equation.

If 6 vans go, no cars are needed
1 vans and 7 cars are numbers that meet the constraints in this situation
If 2 cars go and 5 vans go, there will be extra space.
