The answer to the question
Answer:
See explanation
Step-by-step explanation:
Let the number of adults = a and the number of children = c.
Since the number of people using the pool is 288, we know that a + c = 288
Based on the price information, we know that 1.75c + 2.5a = 528
Combining these two equations allows us to solve for the values of a and c, the process for which follows
a = 288 - c
1.75c + 2.5(288 - c) = 528
c = 256
a = 288 - c = 288 - 256 = 32
a = 32
c = 256
