Answer:
The equation for that models the total money and sandwiches bought is $ 15 = X × $4.50 , And The value of X is 3.33
Step-by-step explanation:
Given as :
The total value of gift card = $ 15
The cost of each sandwiches = $4.50
Let The number of sandwiches bought = X
So, According to question
The total value of gift card = cost of each sandwiches × number of sandwiches bought
Or, The total value of gift card = X × $4.50
Or, $ 15 = X × $4.50
∴ X =
I.e X = 3.33
Hence The equation for that models the total money and sandwiches bought is $ 15 = X × $4.50 , And The value of X is 3.33 Answer

![-\frac{3}{8} +\frac{\sqrt[]{23}i }{8},-\frac{3}{8} -\frac{\sqrt[]{23}i }{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B%5Csqrt%5B%5D%7B23%7Di%20%7D%7B8%7D%2C-%5Cfrac%7B3%7D%7B8%7D%20-%5Cfrac%7B%5Csqrt%5B%5D%7B23%7Di%20%7D%7B8%7D)
or

Step-by-step explanation:

Bring the 8 to the left side so that we equal the equation to 0. To do this, simply substract 8 on both sides.

Where;

![Formula: x=\frac{-b\frac{+}{}\sqrt[]{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=Formula%3A%20x%3D%5Cfrac%7B-b%5Cfrac%7B%2B%7D%7B%7D%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%20%20%7D%7B2a%7D)
Replace. Let x be r
![r=\frac{-3\frac{+}{}\sqrt[]{(3)^2-4(4)(2)} }{2(4)}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-3%5Cfrac%7B%2B%7D%7B%7D%5Csqrt%5B%5D%7B%283%29%5E2-4%284%29%282%29%7D%20%20%7D%7B2%284%29%7D)
![r=\frac{-3\frac{+}{}\sqrt[]{9-32} }{8}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-3%5Cfrac%7B%2B%7D%7B%7D%5Csqrt%5B%5D%7B9-32%7D%20%20%7D%7B8%7D)
![r=\frac{-3\frac{+}{}\sqrt[]{-23} }{8}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-3%5Cfrac%7B%2B%7D%7B%7D%5Csqrt%5B%5D%7B-23%7D%20%20%7D%7B8%7D)
It has no real solution because the square root is negative.
We can say that,
![r=-\frac{3}{8} \frac{+}{}\frac{\sqrt[]{23}*\sqrt[]{-1} }{8}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B3%7D%7B8%7D%20%5Cfrac%7B%2B%7D%7B%7D%5Cfrac%7B%5Csqrt%5B%5D%7B23%7D%2A%5Csqrt%5B%5D%7B-1%7D%20%20%7D%7B8%7D)
![r=-\frac{3}{8} \frac{+}{}\frac{\sqrt[]{23}i }{8}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B3%7D%7B8%7D%20%5Cfrac%7B%2B%7D%7B%7D%5Cfrac%7B%5Csqrt%5B%5D%7B23%7Di%20%7D%7B8%7D)
