Answer:
see below
Step-by-step explanation:
We can determine how much 12 ounces cost by using ratios
5 ounces 12 ounces
-------------- = -------------------
2.35 x
Using cross products
5x = 12*2.35
5x = 28.2
Divide each side by 5
5x/5 = 28.2/5
x =5.64
If she has 10 dollars
5 ounces y ounces
-------------- = -------------------
2.35 10
5*10 = 2.35y
50 = 2.35y
Divide each side by 2.35
50/2.35 = 2.35y/2.35
21.27659574 =y
She can buy 21.3 ounces
A = LW......W = A/L
A = 5/8
L = 10
W = (5/8) / 10
W = 5/8 * 1/10
W = 5/80 = 1/16

12% discont:
12% = 12/100 = 0.12
1 - 0.12 = 0.88
0.88
then the expressión is:
4*0,88d
=3.52 d
d = original cost of each ticket
