    Answer: 30+x+y

    Step-by-step explanation:

    Commutative Property of Addition : a+b = b+a, where a and b are any arbitrary numbers.

    Given : Number of CDs sold by friend on first day = 14

    Number of CDs sold by friend on next day = x

    Total CDs sold by friend = 14 + x

    Number of CDs sold by you on first day = 16

    Number of CDs sold by you on next day = y

    Total CDs sold by you = 16+y

    The expression that shows the total number of CDs sold both days =

    Total CDs sold by friend + Total CDs sold by you

    = 14 + x + 16+y

    = 14 + (x + 16) + y

    = 14 + (16+x) + y [By Commutative Property of Addition.]

    = 14+16+x+y

    = 30+x+y

    Hence, the expression that shows the total number of CDs sold both days:

    30+x+y
