I would say it is A because if you subtract <em>p,</em> the original price by $2.50, you would get <em>d, </em>the discounted price. Look at B u see that you're adding the discount which doesn't make sense. Looking at C, the discounted price of different prices can't always be the same. And finally, D, the discounted price is greater than the original. Also, if you subtract you would get different discounts.

Answer:
y=5x + 21
Step-by-step explanation:
y=5x×b
6= -15+b
b=21
Given:
Measure of a cube = 1 unit on each side.
Dimensions of a space 2 units by 3 units by 4 units.
To find:
Number of cubes that can be fit into the given space.
Solution:
The volume of cube is:

Where, a is the side length of cube.


So, the volume of the cube is 1 cubic units.
The volume of the cuboid is:

Where, l is length, w is width and h is height.
Putting
, we get


So, the volume of the space is 24 cubic units.
We need to divide the volume of the space by the volume of the cube to find the number of cubes that can be fit into the given space.



Therefore, 24 cubes can be fit into the given space.
Answer:
B
Step-by-step explanation:
First, we are decreasing the number so it has to be a decrease.
Next, we divide 7/31 and get around 0.23, which also represents 23 percent.
This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.
We get 100 - 23 = 77, and because it is a decrease we get B.
