Answer:
350 Stamps left
Step-by-step explanation:
First do 5/8*400= 250
Then take 1/5 of it 1/5*250
You end up with 50 so do 250-50= 200 and add the 150 Canadian stamps to get a total of 350 stamps.
Reflection across y=x is a special case transformation

The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices
A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)
Choice A'(1,-5)
