    Answer:

    Total you have to pay: $47.55

    Tax amt: $6.20

    Step-by-step explanation:

    Multiply $41.35 by 1.15

    How this works, when your increasing an amount you first change the percentage to a decimal number. Afterwards you add the decimal number

    Ex: 1 + .15= 1.15

    Or the opposite: 1 – .15= .85

    Then multiply your original number by the number you got from the previous step.

    Ex: $41.35 x 1.15=47.55

    And to find how much you increase just do (Final amount-Initial Amount)
