Question

Billie’s monthly cell phone bill includes the cost of cell phone service, 15% tax on the cost of the cell phone service, and a $9.25 data fee. Billie’s monthly cell phone bill totals $61.
What is the cost of the cell phone service before tax is added?

Answer 1

It would be $46 because when you add the 15% tax to it, the total is $61.
$61-15%=$46. To check $46+15%=61! Hope i helped! :-)
