The plane we want and the plane we're given are parallel, so they share the same normal vector. The normal to is the vector (2, 3, -1), since .

Hi, I'm happy to help!
To solve this, we need to multiply the 60% by the amount of students.
75×60%
Percentages are always out of 100, so we can write 60% like this:

45
