A system of equations has at least one point in common in the solution (unless it is a special case)
A system of inequalities has regions of common solutions. (always an infinite number of solutions)
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.

A couple of rules to review:
#1). Ln(the square root of a number) = 1/2 Ln(the number)
and
#2). e^(Ln of a number) = the number
Now we're all set to solve this thing.
=======================================
<u>Ln( square root of(x+2) ) = 3</u>
From Rule #1: 1/2 Ln (x+2) = 3
Multiply each side by 2: Ln (x+2) = 6
From Rule #2: (x + 2) = e^6
(x + 2) = 403.43 (rounded)
Subtract 2 from each side: <em> x = 401.43</em> (rounded)
