    Answer:

    Maria’s homework time is now 9 hours 12 minutes.

    Step-by-step explanation:

    Since Maria decides to increase her homework time by 15%.

    Then,

    15% of 8 hours = \frac{15}{100} x 8 hours

                            = 0.15 x 8 hours

                            = 1.2 hours

    (Note that: 1.2 hours = 1 hour 12 minutes)

    15% of 8 hours = 1 hour 12 minutes

    her new homework time = 8 hours + 1 hour 12 minutes

                                  = 9 hours 12 minutes

    Maria’s homework time is now 9 hours 12 minutes.
