Question 222481
Amy paid $80.83 for a pair of running shoes during a 15% off sale. What was the regular price?


Step 1.  15% means 0.15.


Step 2.  Let x be the original price.


Step 3.  Let x-0.15x be dollar value that is 15% off.


Step 4.  Then 80.83=x-0.15x since Amy paid $80.83 for a pair of running shoes during a 15% off sale/


Step 5.  Solving yields the following steps


{{{80.83=0.85x}}}


Dividing 0.85 to both sides of the equation yields


{{{80.83/0.85=085x/0.85}}}


{{{x=95.09}}}


Step 6.  ANSWER:  The regular price is $95.09.


I hope the above steps were helpful.
