A washing machine sells for $982.78 in a state that charges 7.85% sales tax and in a city that charges a 3.35% sales tax. What is the total cost of the washing machine?

Step-by-step explanation:

total tax rate = 7.85% + 3.35% = 11.2%

total cost = 1.112×$982.78 ≅$1,092.85

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
