If the y intercepts are also the same, it is just the same line.

Answer:
C
Step-by-step explanation:
The percent markup is basically how much it is MORE than the original.
First, we need to find how much the selling price is more than cost.
Cost = 22.99
Selling Price = 36.99
Markup = 36.99 - 22.99 = $14
How much is the markup, we just found, with respect to cost? That is the markup divided by cost, multiplied by 100 [to convert to percentage]. Shown below:

So, the percent markup = 60.9%
Answer choice C is right.
Answer:
x = 10
Explanation:
A square is a quadrilateral in which all sides are equal.
We are given that:
ABCD is a square
AB = 5x - 10
BC = 2x + 20
Since we're talking about a square, therefore:
AB = BC
5x - 10 = 2x + 20
5x - 2x = 20 + 10
3x = 30
x = 30/3
x = 10
Now, we can check our solution:
AB = 5(10) - 10 = 40 units
BC = 2(10) + 20 = 40 units
We can see that both sides are equal
Hope this helps :)
