Your diagram doesn't clearly define what values correspond to what, can you explain.
Let x = the minutes that Tom has remaining before exceeding 500 minutes.
Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.

x + 230 ≤ 500
Answer: x + 230 ≤ 500
