Okay, to solve this, let's use the variable 'p' to represent the original price:
Because we know the amount of discount and the percentage off, we know that 60% of the original price is $75.
Knowing this, we can write an equation:
0.6p = 75
There are multiple ways to solve this, but I'll just use the method I prefer
6p = 750
p = 750/6
p = 125
The original price of the chess set was $125
