    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
