Answer:

Taylor used 185 minutes of long distance calls.

Step-by-step 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 :

[tex]17+0.08x=31.80[/tex]

Now solving for x,

[tex]0.08x=31.80-17[/tex]

[tex]=> 0.08x=14.8[/tex]

=> x = 185

Hence, Taylor used 185 minutes of long distance calls.
