When solved
(x + 1 < 4) ∩ (x - 8 > -7)
becomes:
(x+1-1 < 4-1) ∩ (x - 8 +8 > -7+8 )
(x < 3) ∩ (x > 1).
and if you change places it will become even more obvious:
( 1<x ) ∩ ( x < 3 )
meaning: x is set of all numbers greater than 1 and less than 3 or otherwise:
{x | 1 < x < 3}
Answer:
Book = $8 each
CD = $5 each
8 x 5 = 40
2 x 5 = 10
= 50
8 x 2 = 16
5 x 3 = 15
= 31

The slope is rise over run. The ski run drops 5, so it would be -5, and the horizontal change of 20 would be the run, so you'd get -5 over 20 then you divide both by 5 and you get your answer of -1 over 4.
