Hi there!
There is an initial cost of $210,000 (which you're just going to pay once)
Then it costs $500 per day to operate.
The number of days is represented by "x".
Your equation in function notation should look like this :
f(x) = 500x + 210,000
There you go! I really hope this helped, if there's anything just let me know! :)
