Sweater: 1/3 = 0,333

1 – 0,6 – 0,333 = 0,067
So the 36$ represents 6,7% of all the money he had at first. (just for you to know 1 represents 100% of the money he had)
Now, you just have to use the rule of three
0,067 = 36
0,333 = x
(0,333•36)/0,067= 179,1$
The sweater costed 179,1$

Answer:
Step-by-step explanation:
16. 180=8x+2x
x=10°
17a. 180=(180-126)+2x+(180-6x)
x=14°
17b. 180=4x+x+65
x=23°
Step-by-step explanation:
5(x+6x-3x)
(5+30-15)x
if you open the brackets, it will be 5x+30x-15x
