For this case we can propose a rule of three and thus find the original price of the cap.
15% --------------> $2.70
100% ----------> x
Where "x" represents the original price of the baseball hat, that is, without offering a discount:
[tex]x = \frac {100 * 2.70} {15}\\x = 18[/tex]
So, we have the original price of the baseball hat is $18
To find the answer we remove 15% of the total price and have:
[tex]0.85 * (18) = 15.3[/tex]
Answer:
The full price of the baseball hat is $15,3
