    Answer: he needs to work for 7 hours.

    Step-by-step explanation:

    Let x represent the number of hours that he need to work to have $220 in his bank account.

    Julio has $127 in his bank account. He gets $30 for his birthday. Since the total amount he wants to have in his bank account is 220, it means that the remaining amount he needs to save is

    220 - (127 + 30) = 63

    He also has a part-time job that pays $9 per hour. It means that the amount that he would earn if he works for 9 hours is 9x. Therefore,

    9x = 63

    x = 63/9

    x = 7
