Help to finish this matrix [table of prices]

[July Fourth]

WHAT THE F!@K???

I'm only just about to upgrade to the Small City in the next 5 days and that only costs £3.6m to do. It's going to cost £682m to actually finish the stadium upgrade fully.

Lol... Yeah and not forgetting the costs to upgrade the stadium all the way to World Arena in the first place which is at least another $700M or something, But you don't need to worry about the costs until you get that far in the game. I finished expanding everything in Level 17.
