    Answer:

    save $3.6, pay $14.4

    Step-by-step explanation:

    A cd costs $18

    If there is a 20% discount, you only have to pay 80% of the original price.

    This means you only have to pay (0.80 x $18=) $14.4 dollars, which means you saved ($18 – $14.4=) $3.6.

    Or you could just do $18 x 0.20 = $3.6
