The price of a bottle of shampoo was marked up 15%, then marked down 4%. If the original price was $4.50, what is the new price? Show your work?

Cost of shampoo = $4.50

% Mark up of Shampoo = 15%

15% Mark up of Shampoo = 15/100 x $4.50 = $0.67

Price of Shampoo 15% Mark up = $4.50 + $0.67 = $5.17

% Mark down of Shampoo = 4%

4% Mark down of shampoo = 4/100 x $5.17 = $0.21

Price of Shampoo 4% Mark down = $5.17 - $0.21 = $4.96

Step-by-step explanation:

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
