What is the constant of proportionality between earnings and time in hours?
To find the constant of proportionality between earnings and time in hours, we can calculate the ratio of earnings to time for any of the given data points.
For example, using the first data point:
Time = 3 hours
Earnings = $86.10
Constant of proportionality = Earnings / Time
Constant of proportionality = $86.10 / 3
Constant of proportionality ≈ $28.70
Therefore, the constant of proportionality between earnings and time in hours is approximately $28.70.
