Answer:
Taylor used 185 minutes of long distance calls.
Explanation:
Let the long distance call minutes be = x
The company charges a flat fee of $17 per month, which includes free local calling plus $0.08 per minute for long distance calls.
Taylor's bill came = $31.80
So, equation forms :
![17+0.08x=31.80](https://img.qammunity.org/2019/formulas/mathematics/high-school/dfavtxqtuw763jm3xaiz0ztbhxyhztb0mi.png)
Now solving for x,
![0.08x=31.80-17](https://img.qammunity.org/2019/formulas/mathematics/high-school/xc78lz22xnthxom6vykpw2vvmlpwvpkcpn.png)
![=> 0.08x=14.8](https://img.qammunity.org/2019/formulas/mathematics/high-school/w0k0bfkpavodfxkg8sp0isi4j0hkg4kmqa.png)
=> x = 185
Hence, Taylor used 185 minutes of long distance calls.
