  answer:

  4000 is the original price

  step-by-step explanation:

  c=cost

  b=base

  r=rate %

  p=percentage

  im using the formula

  c=b-p

  derive the formula p=br

  c=b-br

  10% is the last done, so where doing it first

  3060=b-b10%

  rearrange

  3060=b-0.1b

  (10%=0.1)

  3060=0.9b

  divide .9

  3,400=b

  or

  b= 3,400

  next at 15%

  3,400=b-.15b

  3,400=0.85b

  divide by 0.85

  b=4000
