    Answer

    Find out the total number of minutes they played using associative property.

    To proof

    Associative property of addition

    This property states that

    a + (b + c) = (a + b) + c

    Where a, b, c are the any numbers.

    As given

    Sophia Played for 18 minutes and 26 minutes last week should play the piano for 40 minutes last week

    let

    a = 18 minutes, b = 26 minutes, c = 40 minutes

    Total number of minutes sophia played = a + (b + c) = (a + b) + c

    put the value of a, b, c

    Total number of minutes sophia played = 18 + (26 + 40) = (18 + 26) + 40

    = 18 + 66 = 44 + 40

    = 84 = 84

    satisfy the associative property

    Therefore the total number of minutes sophia played be 84 mintues.

    Hence proved
