The relationship between the two quantities that is the amount of money earned and number of hours worked is direct .
The correct option is B
When two values x and y can be represented in the general form y = kx, where k is the proportionality constant, then there is a proportional relationship between them.
In the equation y= kx, the amount of money a person makes is directly related to the amount of time they work.
FOR EXAMPLE -
Since a person earns $100 for 5 hours of work, we can use this information to find the value of k. Substituting 100 and 5 into the equation results in 100 = k 5. Solving for k produces k = 20. Now we can write a specific equation relating the money earned and the hours worked as y = 20x.
y= 20(18) = $360
