5.12a> No, all customers pay the same price

5.12b> Q = -2 x 300 + 1.200 = 600

5.12c> Turnover = 600 x € 300 = € 180.000,-

5.13
How many people want to buy a ticket at € 200,- (1)
How many people want to buy a ticket at € 400,- (2)

Costs

Proportional variable costs

Variable costs rise proportionally with production

Every extra unit is € 50,- extra costs

TVK = 50q

Break even point

Price per product € 600,-

Fixed costs € 180.000,-, Variable costs per product € 50,-

Revenue = 600q

Costs = 50q + 180.000

Break even point

600q = 50q + 180.000

550q = 180.000

q = 327,2 -> 328

Or 

180.000 / ( 600 - 50 ) = 327,2 -> 328

Break even point

TR = TC

Or 

fixed costs / ( price - variable costs ) 

And always round of upwards to the next number
