A. Pie Chart
They are often used used for comparison and contrast
.
I attached a picture down below to show you how a pie chart compares and contrasts 2 things.
So we need to solve:

First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:

Then:

So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.
<span>-12+2b=12-6b
-12+8b=12
8b=24
b=3</span>
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
