Explanation:

5.

The initial cost is $65.42

25% of 65.42 is 16.355

Add 16.355 + 65.42 and the total cost is: $81.78

6.

The initial cost is $12.50

3.2% of 12.50 is 0.4

Add 0.4 + 12.50 and the total cost is: $12.90

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
