the fixed expenditure for the activity is 510, so you have to deduct 510 first
1150- 510 = 640
the expenditure for food and drinks for each participant
640/12 = 53.33333-----------
that means the food and drinks is only enough for 53 people
so the greatest senior citizens that can be invited are 53
