Recall that a dilation with center (0, 0) and scale factor
maps
onto
.
Now, triangle ADE is formed by

Whereas triangle ABC is formed by

In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.
This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.
The answer is 4.77 euro.
First I found out what the cost of one pen was.
I did: 6.36/12 pens
The answer was: 0.53
Then I did 0.53 times 9
