Correct option is D![\frac{P}{(0.8)(1.08)}](/tpl/images/1381/8178/659d3.png)
Step-by-step explanation:
Let the laptop's original cost be = L
After 20% discount its price will be (100 - 20)% × L = 0.8L
8% sales tax on this price = (100 + 8)% × 0.8L = 1.08 × 0.8L
So, p = 1.08 × 0.8L
⇒ L =![\frac{p}{(0.8)(1.08)}](/tpl/images/1381/8178/7e41d.png)
