Answer:
11.33
Step-by-step explanation:
First find the markup
8.80 * 25%
8.8 *.25 = 2.20
The new price is 8.80+2.20 = 11
Now find the tax
11*.03
.33
Add the tax to the new price
11+.33
11.33
First you must acknowledge that you are dealing with a line therefore you must write linear equation or linear function in this case.
Linear function has a form of,

Then calculate the slope <em>m</em> using the coordinates of two points. Let say <em>A(x1, y1)</em> and <em>B(x2, y2)</em>,

Now pick a point either <em>A</em> or <em>B</em> and insert coordinates of either one of them in the linear equation also insert the slope you just calculated, I will pick point <em>A</em>.

From here you solve the equation for n,

So you have slope <em>m</em> and variable <em>n</em> therefore you can write down the equation of the line,

Hope this helps.

I think it’s 39.81. I don’t know if that was the answer to YOUR question but I’m pretty sure that’s comparing the energy
Answer is A and C
Imagine your square has an area of 64,
That means it’s sides are 8 x 8
So only rectangles that are 8inches x 8 inches or less will fit. A and C have these dimensions, they will fit. The other two will not. See my attachment, the green rectangle must fit inside the 8 x 8 square.
