Answer:
$1,100
Step-by-step explanation:
Since we that 75% less than the original price, or 15% of the original price*, is equal to $165, we can set up an equation like this, where [tex]x[/tex] represents the original price:
[tex].15x=165[/tex]
Now, just solve for [tex]x[/tex] by dividing both sides by .15, the equivalent of 15%:
[tex]x=\frac{165}{.15}\\x=1100[/tex]
Therefore, the original price of the suit was $1,100.
*The reason that we use .15 instead of .75 is that when something is on sale with 75% of the original price cut off, 15% of the original price remains. That's why [tex].15x=165[/tex].
