There are 4 people in Molly's group.

Step-by-step explanation:

Let,

x be the number of people.

Individual ticket price = $42

Price after discount = $30

Discount per ticket = $3

Discount for x people = 3x

According to given statement;

42-3x=30

Subtracting 42 from both sides

$42-42-3x=30-42\\-3x=-12\\$

Dividing both sides by -3

$\frac{-3x}{-3}=\frac{-12}{-3}\\x=4$

There are 4 people in Molly's group.
