We can start by using the following formula to find the original price:
Original price = Sale price / (1 - (Discount percentage / 100))
To use this formula, we need to convert the discount percentage from 26% to a decimal. We can do that by dividing 26 by 100.
Discount percentage as decimal = 26 / 100 = 0.26
Now we can use this value in the formula:
Original price = $469.16 / (1 - 0.26) = $469.16 / 0.74 = $630.22
So the original price of the television set was $630.22.
