Answer:
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.
Yes
the given function is exponential, because x is the exponent of 3

x = 8.66
Apply pythagorean theorem to find the value of x.
Thus:
x² = 14² - 11²
x² = 75
x = √75
x = 8.66025404
x = 8.66 (nearest hundredth)
