Answer:maybe 249.6 children and 179.4 adults
Step-by-step explanation:
250 children and 179 adults swam at the public pool that day.
C = number of children, which is also 1.75 each.
A = number of adults, which is also 2.50 each.
Since 429 used the public swimming pool, we know that C + A = 429.
Or, we can also use the expression:
1.75c + 2.50a = 885 (admission totaled 885.)
We also know that:
A = 429 - C
Take this expression substitute A with it into the original expression. We would get:
1.75c + 2.50 (429 - C) = 885
2.50 * 429 = 1,072.5
We would then get the following expression:
1.75c + 1,072.5 - 2.50c = 885
2.50 - 1.75 = 0.75
0.75c + 1,072.5 = 885
This also means:
0.75c = 1,072.5 - 885
1,072.5 - 885 = 187.5
Use distributive property to find C:
0.75c = 187.5
C = 187.5/0.75
= 250
C = 250
Now we find A:
A = 429 - C
Now we know what C is, we can calculate A using the expression above.
A = 429 - 250
= 179
Therefore, 250 children and 179 adults swam at the public pool that day.
I hate asking for Brainliest, but I did spend a lot of time on this question so I would appreciate it if I did get Brainliest or at least get voted 5 stars. If not, that’s fine! I hope this helped!
