Problem Analysis

We are given the following information: - There are 380 spectator seats in the swimming pool. - 158 relatives came to support the fourth-grade students, which is 12 fewer than the number of friends. - There are 40 acquaintances who want to attend the competition.

We need to determine if there will be enough space for the acquaintances.

Solution

To solve this problem, we need to calculate the total number of people who came to support the fourth-grade students and compare it to the number of spectator seats available.

Let's calculate the total number of people who came to support the fourth-grade students: - The number of relatives is given as 158. - The number of friends is 12 more than the number of relatives, so it is 158 + 12 = 170. - The number of acquaintances is given as 40.

The total number of people who came to support the fourth-grade students is 158 + 170 + 40 = 368.

Now, let's compare the total number of people to the number of spectator seats available: - The number of spectator seats available is given as 380.

Since the total number of people who came to support the fourth-grade students (368) is less than the number of spectator seats available (380), there will be enough space for the acquaintances.

Answer

Yes, there will be enough space for the acquaintances, as the total number of people who came to support the fourth-grade students is less than the number of spectator seats available.
