1. A radio cost $20, Harold buys it for $12, what percent off the original price did he receive? 2. Dave reported 7 out of 35 members of the club paid their dues. What percent paid their dues?

3. Last year Earnie earned $25,000. His new job pays $28,000, what percent raise did he receive?

i can answer this question sweetie!

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
