Let's call the original price [tex]o[/tex] and the sale price [tex]s[/tex]. Given the information in the problem, we can say:
[tex]o - s = 125[/tex]
(The sale price subtracted from the original price is the sale on the product, which we know is 125.)
We know the value of [tex]s[/tex], which is 875. If we substitute this into the equation we found, we can find [tex]o[/tex], as shown below:
[tex]o - s =125[/tex]
- Original equation
[tex]o - 875 = 125[/tex]
- Substitute in 875 for [tex]s[/tex]
[tex]o = 1000[/tex]
- Add 875 to both sides of the equation
The original price is $1,000.
