30 POINTS!!!!! WILL MARK BRAINLIEST!

Karel and her family have just moved into a new neighborhood. Karel wants to earn money by baby-sitting for families with young children. She asked other students her age how much they charged for babysitting. The results are listed in the chart below.

LOOK AT CHART!

1. Suppose Karel wants to be the least expensive babysitter in the neighborhood. How much should she charge? This response will be graded for the correct numerical information.

2. Suppose Karel wants to charge the same hourly rate as most of the other baby-sitters. How much should she charge? This response will be graded for the correct numerical information.

3. Suppose Karel wants her hourly rate to be higher than the rate of half of other baby-sitters, but lower than the hourly rate of the rest of the babysitters. How much should she charge? This response will be graded for the correct numerical information.

4. In addition to the babysitting rates charged by others, what might Karel consider when she sets her rates? Respond in complete sentences, not only with calculations. Write as if you are verbally explaining what you are thinking.

1. She should charge less than $2.00.
Since the cheapest babysitter charges $2.00, Karel should charge less to be cheapest.

2. $3.25
Most of the other babysitters charge $3.25.

3. $2.50
The median of this set is $2.50, so she should be at the median of $2.50 for this question.

4. Karel should also consider the range of the hourly costs of the babysitters. For this, she would charge $1.00.
