Answer:

32 points

Step-by-step explanation:

Set up an equation based on the given information

He started with 30 points:  30

Gained 'p' points:   p

Lost 12 points:  -12

Now he has 50 points:   50

So his point total can be described by the equation..

30 + p - 12 = 50

Now solve for p

  p + 18 = 50

      p = 32
