See the photo attached above

Answer 2

Answer: There were 60 people in the picnic.

Explanation:

Let there are x people in the picnic,

Since, the number of people who ate the hot dog for a lunch = 30 % of the total number of people in the picnic

= 30% of x

= 0.3 x

According to the question,

0.3 x = 18

⇒ x = 60 ( Dividing both sides by 0.3)

Thus, there were 60 people in the picnic.
