Wendy is paid $9 per hour and plans to work between 20 and 25 hours per week. Identify the independent and dependent quantity in the situation. Find reasonable domain and range values.

Answer 1

Independent quantity: hours worked per week
Dependent quantity: amount of money earned

Reasonable domain values:
Hours worked per week: 20 ≤ hours ≤ 25 (since Wendy plans to work between 20 and 25 hours per week)

Reasonable range values:
Amount of money earned: 20 hours * $9/hour = $180 (minimum)
Amount of money earned: 25 hours * $9/hour = $225 (maximum)
