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]
