Question

Sally has a part time job mowing lawns so she can save money for a new car. She charges $5 per hour. What numbers make sense for the domain and range.

Answer 1

Answer:

Step-by-step explanation:

The number of hours worked, h, could be zero or greater:  [0, 40), where "40" is the upper cap on the number of hours she works.

The range consists of all possible total earnings amounts:  [$0, $1000).

Answer 2

Answer:

Independent: Amount of hours she works

Dependent: Amount of money she makes

Step-by-step explanation:

The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.

The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.
