Answer:
12y
Step-by-step explanation:
(a) need to find the number of books, we'll call it "b". then the money (6w) minus the cost of books (17b) equals change left over (w)
6w - 17b = w
6w - w = 17b
5w = 17b
(5/17)w = b
(b) if w = 34
(5/17) *34 = b
10 = b
20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
To solve this, you would do:
x + 75% * x = 35
7/4 * x = 35
x = 20
