Question

Bill earns $12 per hour and works at most 40 hours per week. Identify the independent and dependent quantity in the situation, and find reasonable domain and range values.
please help me

Answer 1

The situation can be modeled as a linear equation:
 y = 12x
 Where
 y: amount of dollars.
 x: hours worked.
 Independent variable: x (hours worked).
 Dependent variable: y (amount of dollars).
 he works at most 40 hours per week
 Domain: x belongs [0, 40]
 To determine the range, we must calculate how much Bill earns per week
 y = 12 * (40) = 480.
 Range: y belongs [0, 480]
 answer
 Independent variable: x (hours worked).
 Dependent variable: y (amount of dollars.
 Domain: x belongs [0, 40]
 Range: y belongs [0, 480]
