The
rate of earning money for both activities will be calculated by dividing the
amount earned by the total time spent for each of the activity.
Babysitting:
rate = ($30 / 5 hours ) = $6 / hour
Doing
chores: rate = ($28 / 4 hours) = $7 / hour
Thus, Holly is able to earn money faster when doing the
chores compared to when she do the babysitting if she work for the same amount
of time for each.
