identify the independent and dependent variables

Question

 Let P(t) denote the number of people P at Copacabana Beach in Rio de Janeiro, T hours past midnight on a specific day . 

 Identify the independent and dependent variables 

Answer 1

The dependent variable is the number of people on the beach, P(t) .

 

The independent variable is presumably the time, expressed as the number of hours past midnight.

 

P(t) = 24.00 + T

 

(I used 24.00 as midnight - it's military time)
