If the total cost of a package of paper clips including 8% sales tax is $2.70, then what was the price before tax was added

Let the price (before tax )  = P

 

And the tax  was  8% of P  =  .08P

 

So

 

P   + .08P   = 2.70      simplify

 

P (1 + .08)  = 2.70

 

P (1.08)  = 2.70      divide both sides by  1.08

 

P  =  2.70 / 1.08   = 2.50   =  $2.50

 

 

cool cool cool
