b. 75

Step-by-step explanation:

Calculation for how many people must attend the festival

Using this formula

Numbers of people to attend the festival=Expenses/Charges

Let plug in the formula

Numbers of people to attend the festival=($115+$110)/$3

Numbers of people to attend the festival=$225/$3

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
