    Answer:

    $2.50 coupon is better as it gives a cheaper sale price.

    Step-by-step explanation:

    Price of good = $12

    Sale price = price of good – coupon

    Coupon 1 :

    $2.50

    Sale price = $12 – $2.50 = 9.50

    Coupon 2:

    15% off

    Sale price =. (100 – 15)% * 12

    = 0.85 * 12

    = $10.2
