    Answer:

    5%.

    Step-by-step explanation:

    220 is the starting value.

    209 is the decreased value.

    To calculate a percentage decrease, you must first subtract the starting value from the decreased value.

    220 – 209 = 11.

    Then, divide the difference by the absolute value of the starting value.

    **ABSOLUTE VALUE – A NUMBER’S DISTANCE FROM 0.**

    The absolute value of 220 is 220.

    11 / 220 = 0.05.

    Lastly, multiply the quotient by 100

    0.05 × 100 = 5.

    Therefore, the price was reduced by 5%.

    The product is positive; this means there was a decrease in price, and not an increase. Ex. 5

    If the product is negative, this means there was an increase in price, and not a decrease. Ex. -5
