The independent quantity is the , and the dependent quantity is the _________ and the dependent quantity is the _________ The function representing the situation is _________

Answer 1

independent quantity (x) is number of races won
dependent quantity f(x)...or y is total virtual money
the function is : f(x) = 500x + 5000 or y = 500x + 5000

Answer 2

The game gives each player an initial amount of $5,000 in virtual money. After that, a player gets $500 in virtual money for each race won. This $5000 is fixed.

Let the races won be x

So, the function that represents the amount of virtual money a player has in terms of the number of races won becomes :

`f(x)=500x+5000`

The independent quantity (x) is : the number of races won

And the dependent quantity f(x) or y is : the total virtual money earned
