Answer:
e^2 -7 = x
Step-by-step explanation:
2=ln(x+7)
Raise each side to the base of e
e^2 = e^ln (x+7)
The e^ln cancel
e^2 = x+7
Subtract 7 from each side
e^2 -7 = x +7-7
e^2 -7 = x

The original price of phone is $ 315.76
<em><u>Solution:</u></em>
Given that Mica bought a new smart phone for $ 258.13.
That was the price after his 18.25% discount
<em><u>To find: original price of phone</u></em>
From given question,
price after discount = $ 258.13
discount = 18.25 %
Let "x" be the original price of phone
price after discount = original price - discount




Thus original price of phone is $ 315.76
