Answer 1

Answer:

Correct option is D $\frac{P}{(0.8)(1.08)}$

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 = $\frac{p}{(0.8)(1.08)}$
