Answer:
B
Step-by-step explanation:
When you divide each of the prices by the amount of candy bars, B is the lowest. The price for 1 candy bar with A's price is 1.75. The price for 1 candy bar for B's is 1.71. The price for 1 candy bar with C's is 1.73 and the price of 1 candy bar for D's is 1.74. Again, B has the lowest price for 1 candy bar so the correct answer is B.
The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.
We need to find the solution to the given function.
<h3>How to find the solution to the function from the graph?</h3>
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be at the point where the two lines intersect.
From the given graph we can see that the two functions are intersecting at (–2,–4) and (4,8).
The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.

Answer:
You have 80 yards left to run.
Step-by-step explanation:
To solve this problem, we first must realize that if you have completed 80% of the run, that you have 20% left (this is because 100%-80% = 20%).
Next, we must find 20% of 400 yards. We must remember that in math, the word "of" represents multiplication. We also know that 20% = 20/100 = 0.2.
To find 20% of 400 yards, we can perform the following operation:
20% * 400
0.2 * 400
80
Therefore, you have 80 yards left.
Hope this helps!
