15x25 = 375
15 x 30 = 450
That's not lazing about if you got 800 in 15 missions, you're giving this poor person false hope.
Lazing about, if the total score of a type matchup test is 300 youll get 25 points. I'd say about half of them don't reach that outside of rush hour, so at minimum youre looking at 20 rounds an hour (3mins each) at 10 - 20 FC each time (being lazy) so 200 - 400 FC an hour MINIMUM (can't accurately say because the total score thing and the time remaining thing). However if you participate with enough time left and get 16 points (will require approx. 2min 15sec if you're good at the game) which is full credit aka 25 FC, then youll earn a minimum of: 700 - 900 FC an hour.
It's not really that hard, you just need to be willing to put in some effort one day and build up the bank.
