The distance depends on the time.
So now we need to find the constant of variation or the constant of proportionality.
To do so we must find y(the dependent variable) and x(the independent variable).
To find the constant(k) we must find y/x
Since y/x=k
Then 2.25/.75=k
k=3
Answer:
y(t) = 391 - 30t
Step-by-step explanation:
The weekly difference is 391-361 = 30
y(t) = 391 - 30t.
With t being the number of weeks.
