    Answer:

    15 napkins

    Step-by-step explanation:

    Let n be the no. of napkins

    1.50n = 2.50 + 20

    1.50n = 22.50

    n = 22.50/1.50

    n = 15

    Answer:

    She bought 15 napkins

    Step-by-step explanation:

    First find the price before coupon

    1.5 * n  where n is the number of napkins

    Then subtract the coupon

    1.5n – 20

    This is the price she paid before tax

    1.5n -20 = 2.5

    Solving for n

    Add 20 to each side

    1.5n -20+20 = 2.5+20

    1.5 n= 22.50

    Divide each side by 1.5

    1.5n/1.5 = 22.5/1.5

    n =15

    She bought 15 napkins
