Holly earns $30 for babysitting 5 hours. she earns $28 when she does chores for 4 hours. which compares the unit rates?

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. 

The unit rate for doing chores is $1 more than the unit rate for babysitting.

Step-by-step explanation:

30 divided by 5=6  So that means it was six dollars for babysitting.

28 divided by four=7  So that means it was seven dollars for babysitting.
