Question

A phone company charges a flat fee of $17 per month, which includes free local calling plus $0.08 per minute for long distance calls. The Taylor's phone bill for the month is $31.80. How many minutes of long distance calling did they use during the month?

Answer 1

x= minutes spent on the long distance phone calls.

17 + 0.8x=$31.80
-17 -17
—————————
.08x = 14.80
——— ———
.08 .08 x=185


That would be 185 minutes of long distance calling during the month.

Answer 2

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`

Now solving for x,

`0.08x=31.80-17`

`=> 0.08x=14.8`

=> x = 185

Hence, Taylor used 185 minutes of long distance calls.
