    32+10x - (21+12x)

    Step-by-step explanation:

    We are given that:

    Amount MIkayla has in here piggy bank initially = $32

    Money earned by Mikayla per week = $10

    Money earned by Mikayla in x weeks = 10x

    Total money MIkayla has after x weeks = 32+10x

    Amount Jessica has in here piggy bank initially = $21

    Money earned by Jessica per week = $12

    Money earned by Jessica in x weeks = 12x

    Total money Jessica has after x weeks = 21+12x

    Comparing,

    In order to compare, we subtract the money earned by Jessica from that earned by MIkalya,

    The final expression would be:

    32+10x - (21+12x)
