Caroline babysat for two families - the Nelsons and the Smiths. Use the info below to compare her earnings.
algol13

Answer:

She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.

Step-by-step explanation:

To solve this problem you must find the hourly rate she earns at the Smiths.  This will allow you to compare to the hourly rate that is given for the Nelsons.  To find the Smiths hourly rate divide $39 by the 6 hours she babysat there.  This will have the hourly rate.  39/6=6.5.  This means she earns $6.50 an hour for the Smiths.  When comparing the rates it is clear that she earned 25 cents more at the Smiths.
