For 27 since all they did was add a zero on the end of the first number (9,554), you just add that zero to the end of you quotient to make 95,540 / 562 = 170
For 28 the answer is 110.59 (rounded to nearest hundredth) because you take the distance between the moon and earth and divide it by the width of the moon 384,400 / 3,476 = 110.58688

Answer:
5 dollars more
Step-by-step explanation:
Right now, Jake is using a material that gives him 27 dollars of profit per deck. If he switches to a new material, the profit that he gets is expressed by the function y = 32x. To make this a bit easier to understand, let's switch out y and x for some easier words.
profit = (number sold)*32
This function shows that for each deck with the new material, Jake will get 32 dollars profit. Since the question asks for how many more dollars, we can get the answer by
32 - 27 = 5.
If you still don't understand it, you can think of his old material in a function too:
y = 27x or profit = (number sold) * 27.
Comparing that one with the one above with the new material, we can tell that 32 represents the profit per deck.
I believe there is something wrong with the fourth equation. It shouldn"t be equal the first equation. It should be: -ac = - db
Let's calculate the linear equations of AB & CD
x/(x-b) = (y-a)/y
xy = (x-b)(y-a)
-ax-by+ab=0
y=-ax/b+a
(x+c)/x= y/(y+d)
(x+c)(y+d)=xy
dx+cy+cd=0
y=-dx/c - d
-a/b = -d/c in other words:
-ac = -db (Resembling the fourth equation)
