The answer is B because the absolute value of -8 is 8. Hope this helps!

Step-by-step explanation:

<span>Using what's given, you'd have $2800 = p x 0.04 x 3.5. </span>
<span>We don't know the principle so you'd leave the variable there and convert 4% interest to 0.04. Solve by getting 2800 = p(0.14) then divide each side by 0.14 and get p=20,000. So your principle, or the amount deposited, should be $20000. You can solve by plugging in your answer (20000 x 0.04 x 3.5 = 2800)
</span>Interest = Principal * rate * time
<span>2800 = x * 4% * 3.5 </span>
<span>2800/(4% *3.5) = x </span>
<span>20000 = x

Answer:
Number of hot dogs sold = 56
Number of hamburgers sold = 52
Step-by-step explanation:
Let
Number of hot dogs sold = x
Number of hamburgers sold = y
We can make equation from given equations:
(Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )
(Together you sold 108 hot dogs and hamburgers.)
Now we cam solve these system of equations to find value of x and y
![0.50x+y=80--eq(1)\\x+y=108--eq(2)](https://tex.z-dn.net/?f=0.50x%2By%3D80--eq%281%29%5C%5Cx%2By%3D108--eq%282%29)
Subtract both equations to get value of x:
![0.50x+y=80\\x\:\:\:\:\:\:\:\: + y=108\\-\:\:\:\:\:\:\:\: -\:\:\:\:\:\: -\\---------\\-0.5x=-28\\x=\frac{-28}{-0.5}\\x=56](https://tex.z-dn.net/?f=0.50x%2By%3D80%5C%5Cx%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%20%2B%20y%3D108%5C%5C-%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%20-%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%20-%5C%5C---------%5C%5C-0.5x%3D-28%5C%5Cx%3D%5Cfrac%7B-28%7D%7B-0.5%7D%5C%5Cx%3D56)
We get value of x = 56
Now putting value of x in equation 2 to find value of y
![x+y=108\\56+y=108\\y=108-56\\y=52](https://tex.z-dn.net/?f=x%2By%3D108%5C%5C56%2By%3D108%5C%5Cy%3D108-56%5C%5Cy%3D52)
So, we get y = 52
Therefore,
Number of hot dogs sold = x = 56
Number of hamburgers sold = y = 52
C. I believe there is only 1 times itself to equal 157.
