Answer:
Suppose that the batch has N liters of paint.
we know that the recipe is:
1/2 of red paint
1/3 of yellow paint
1/6 of white paint.
Then, out of the N liters, 1/2 is red.
This means that we must use:
N/2 liters of red paint.
And the same for the other two colors:
N/3 liters of yellow paint
N/6 liters of white paint.
When we add those 3, we have:
(N/2 + N/3 + N/6) = (3*N/6 + 2*N/6 + N/6) = N.
Now, if for example N = 2
Then the batch has 2 liters of paint, this would mean that we must use:
2/2 liters of red paint
2/3 liters of yellow paint
2/6 liters of white paint.
Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.

23.50
+
(
$
23.50

)
(we divide by 100 to get the number out of a percent)
=

23.50

(

23.50

38.31
Ok now that we have the number after the price increase, we now need to find the final answer after a discount of

%
(do the exact same idea as above but switch the sign)

Answer:
B. NO
Step-by-step explanation:
Figure B can only be a scale copy of Figure A if the ratio of their corresponding side lengths are equal.
Let's find out:
9/3 = 3
7.3/2.2 ≈ 3.3
Thus:
9/3 ≠ 7.3/2.2
Since the ratio of their corresponding side lengths are not equal, therefore Figure B is not a scale copy of Figure A.
The answer is NO.
An equation is a number sentence with any letter of the alphabet as a variable. for example 3 + y = 6. In this case, y =3
