<h3>How do we represent inequalities?</h3>Inequalities are expressed using either the '>' or '<' symbols.
• The symbol '>' means "greater than". For example, 6 > 3, which means '6 is greater than 3'.
• The symbol '<' means "smaller than". For example, 5 < 9, which means '5 is smaller than 9.
In this example, if the baker needs more than 120 minutes, and <em>m</em> represents the number of minutes, then:
.
This inequality means 'm is greater than 120'.

Answer:
$210
Step-by-step explanation:
The first thing we can do is to add the $25 back on to the total cost.
25 + 115 = 140.
We do this because he Sam used a gift certificate on the ski's that are already 2/3 of the original price.
Now, to find the original price we can use this equation:
X represents the original price.
To solve this equation you would flip 2/3 to 3/2 and multiply that by 140, as seen below:
Now you can solve:
We can check this answer by multiplying 210 by 2/3
(210)(2/3) = 140
Remember, Sam used a gift certificate for $25
140 - 25 = $115
Therefore, the original price of the skis is $210.
