Pizza Anyone?
A club of 30 members ordered pizza. One of the members commented that it 5 people had not attended, the price per person would have been $2 more.
What was the total bill for pizza?

Let the total cost be c. The cost/head would have been c/30,
it is now c/25:
c/25 = c/30 +2
=> 30c = 25c +2*25*30
=> 5c = 2*25*30
=> c = 300
Confirmed
25*(x+2)=30*x
50=5x
10=x
Total=25*(10+2)=30*10=300
Answer:300
