    H (x) = 0.85x - 2.00

    Step-by-step explanation:

    The original price of an item, x dollars, is discounted by 15%.

    Let x be the original price of an item

    15% = 0.15 discount, so discounted amount is 0.15x

    Now we subtract discounted amount from original amount

    x - 0.15x = 0.85x

    A coupon for $2.00 off is applied to the discounted price.

    $2.00 is off, so we subtract 2

    Function becomes H (x) = 0.85x - 2.00
