The number of soda bottles Katie bought is 6
The given parameters are:
- Large Pizza = $14.99
- Soda = $1.50 per bottle
- Total cost = $23.99
Assume the number of soda bottle is x.
So, we have:
![Total = Pizza + Soda \times x](https://tex.z-dn.net/?f=Total%20%3D%20Pizza%20%2B%20Soda%20%5Ctimes%20x)
This gives
![23.99 = 14.99 + 1.50\times x](https://tex.z-dn.net/?f=23.99%20%3D%2014.99%20%2B%201.50%5Ctimes%20x)
Subtract 14.99 from both sides of the equations
![9 = 1.50\times x](https://tex.z-dn.net/?f=9%20%3D%201.50%5Ctimes%20x)
Divide both sides of the equations by 1.5
![6=x](https://tex.z-dn.net/?f=6%3Dx)
Rewrite the equation as
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
Hence, the number of bottles is 6
