Answer:
Step-by-step explanation:
Let x represent the number of children that would swim at the swimming party.
The cost of having a swimming party is $6 per child plus $150 to rent the pool. This means that the total cost of swimming for x children would be
6x + 150
The cost of swimming for 8 children would be
6 × 8 + 150 = 48 + 150
= $198
The cost of swimming for 25 children would be
6 × 25 + 150 = 150 + 150
= $300
