    Answer:

    She will pay $30.8448.

    Step-by-step explanation:

    Consider the provided information.

    The price of the sweater is $90.

    She gets a discount of 30% it means she needs to pay only (100-30)%=70% of $90.

    70% of $90 = 0.7\times 90 = 63

    Now she gets a discount of 20% it means she needs to only 80% of $63.

    0.8\times 63=50.4

    If she gets a discount of 10% on $50.4 it means she needs to pay 90% of 50.4

    0.9\times 50.4=45.36

    If she gets a discount of 15% on 45.36 it means she needs to pay only 85% of 45.36

    0.85\times 45.36 =38.556

    Now she gets an additional 20% holiday Bones Buck discount it means she needs to pay 80% of 38.556

    0.8\times 38.556=30.8448

    Hence, she will pay $30.8448.
