Answer:
The original price of the laptop before discount and tax was $718.46.
Step-by-step explanation:
Let's work backwards from the sale price to find the original price:
1. First, we need to remove the effect of the additional 8% tax.
We can do this by dividing the sale price by 1.08 (100% + 8% = 108%) :
$505.44 / 1.08 = $467.00 (rounded to the nearest cent)
2. Now we need to remove the effect of the 35% discount. We can do this by dividing the price before discount by 0.65 (100% - 35% = 65%) :
$467.00 / 0.65 = $718.46 (rounded to the nearest cent)
