ΔABC is translated to ΔA'B'C'

A(0,3) , B(-2,2) , C(-1,1)

A'(3,0) , B'(2,2) , C'(1,1)

So, if the coordinate of the pre-image is (x,y)

The coordinate of the image will be (y, -x)

Which mean the rule will be (x,y)→(y,-x)

The previous rule is the rule of rotation 270° counterclockwise

So, the answer is 270° around the origin

Verdich [7]

Levant traded 270 american dollars and received 3000 Mexican pesos. This means that:
1 Mexican peso = (270 x 1) / (3000) = 0.09$

Therefore,
100 pesos will be worth 100 x 0.09 = 9$

Based on this, he will receive 9$ when exchanging 100 pesos for dollars.
