Where,
predicted value of lead content when traffic flow is 15.


Calculating thet-critical value
The lower predicted value 

When
of CI use as the expected lead content:

Sweater: 1/3 = 0,333
Jeans: 3/5 = 0,6
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$
