Question 923855
For his long distance phone service, Greg pays a 
$5
 monthly fee plus 
9
 cents per minute. Last month, Greg's long distance bill was 
$11.12
 . For how many minutes was Greg billed?
--------
Bill = 9 + 0.09x = 11.12
---
Bill = 0.09x = 2.12
x = 23.56 minutes
-----
Checking:: 23.56*0.09 + 9 = $11.12
----------------
Cheers,
Stan H.
