PRICE, 3 dollars per person
QUANTITY, 30 persons
COST, 150 dollars

PQ=C

Note that 3%2A30%3C%3E150, but instead 3%2A30=90

Better would be, there is a minimum base cost no matter how many people came.
C=3%2A30%2Bb
150=3%2A30%2Bb
b=150-90
b=60

Model Equation would be C=PQ%2Bb
or
C=3Q%2B60

Formulation of the problem is fantastically  BAD.

As it is worded, printed, posted and presented,  it is only good to through it to a GARBAGE BOX.


Now let me warn you in advance VERY SERIOUSLY : If I see such a GIBBERISH next time, I will really redirect it to a GARBAGE BOX
without any additional explanations.


In addition, if I see such a GIBBERISH next time, I will write to the managers of this project asking them to replace you
for your inability to post problems correctly to the forum.
