Toni spent $72.25 getting her hair styled for the prom. The salon was having a 15% off sale. How much was the original price of Toni's hair treatment?

The original price of Toni's hair treatment was $85.

Step-by-step explanation:

From the information given, you know that $72.25 is the price with the 15% discount:

100%-15%=85%

This means that $72.25 representes 85% of the original price and with this, you can use a rule of three to find the price that represents 100%:

72.25→ 85%

  x     ← 100%

x=(72.25*100)/85

x=85

According to this, the answer is that the original price of Toni's hair treatment was $85.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
