Question

Bill earns $12 per hour and works at most 40 hours per week. Identity the independent and dependent quantity in the situation, and find reasonable domain and range value

Answer 1

Independent quantity: Number of hours worked per week
Dependent quantity: Amount of money earned

Reasonable domain values:
- Number of hours worked per week: 0 ≤ hours ≤ 40 (as Bill works at most 40 hours per week)
- Amount of money earned: $0 ≤ earnings

Reasonable range values:
- Amount of money earned: $0 ≤ earnings ≤ $480 (as Bill earns $12 per hour and works at most 40 hours per week)
