Multiple choice to determine payment

@Hansgirlgangcraf - it looks like your logic evaluates in sequence: 

• if a&b then multiply the price x2 = 25*2 = the now current value of price (ie 50) 
• if a&c then multiply price *2 = 50* 2 = 100 = the now current value of price
• if a&b&c then multiply price x3 = 100 *3 = 300= now current value of price
• if B&C then multiply price  x 2 = 300 x 2 = 600 

that is what happens if all the conditions are true

you may be better served to use the following: 

• if A then add 25 to price
• if B then add 25 to price
• if c then add 25 to price 

that way the max that would be in the price variable is 75 … 

that is much simpler
