4. The school purchased 35 binders for their academic advisors. The binders that were ordered came in two different sizes, one-inch and two-inch. The one-inch binders cost $8 each and the two-inch binders
cost $15 each. How many of each binders were purchased if the school spent a total of $455?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
