What is the approach to solving this kind of problem?: "A shirt costs $12 after a 15% discount. What was the original price of the shirt?"

Respuesta :

eah
Original price = 100%

100% - 15% = 85%

So $12 = 85% of original price

[tex]x \rightarrow original \ price[/tex]

12 = 85/100x
12 = 0,85x
12/0,85 = x
14,12 ≈ x

[tex]ANSWER = \$14,12[/tex]

The approach is ...

   $12 =  85% of (original price)

   $12 = 0.85 x (original price)

Divide each side by  0.85 :

   $12 / 0.85  =  original price
