Answer:

  • $695.65

Step-by-step explanation:

We know that:

  • 100% + 15% = 800

Work:

  • 115% = $800
  • => 1% = $800/115
  • => 100% = 800/115 x 100
  • => Cost = 800/23 x 20
  • => Cost = $16000/23
  • => Cost = 695.65 (Rounded to nearest hundredth)

Hence, the cost of Laptop before tax was $695.65.
