What is the constant of proportionality? Write your answer as a whole number or decimal.

The constant of proportionality is 3 (multiplied by 3 to be exact)

Lets t be the time, and w the weather.
The t, is dependent of the situation because as the time t, increases, also the earnings increase ($7 an hour)
The w, is independent of the situation because nothing is said about it, nothing like, she doesn't work if its cloudy, or gains more money if it is hot.
