Ok, so you eat 1/3 of the pizza the first night. That would leave 2/3 of the pizza uneaten. 2/3 is equal to about 0.67.
You're now going to eat a quarter of what's left of the pizza. A quarter of 2/3 is 2/12 which is 1/6. Subtract 1/6 from 2/3... 4/6 - 1/6 = 3/6 = 1/2. The pizza is already half gone.
At the rate you've decided to eat the pizza, it's going to be half gone after 2 nights.

Answer:
There were 169 children at the pool.
Step-by-step explanation:
Given:
Total number of people = 550
Price per child = $1.75
Price per adult = $2.25
Total cost of the admission receipts = $1153.00
Let the number of children be 'x' and number of adults be 'y'.
As per question:
Total number of people is equal to total children and total adults. So,
![x+y=550-----------(1)](https://tex.z-dn.net/?f=x%2By%3D550-----------%281%29)
Total cost of admission is equal to the sum of cost of total children and total adults. So,
![1.75x+2.25y=1153-----------(2)](https://tex.z-dn.net/?f=1.75x%2B2.25y%3D1153-----------%282%29)
Multiplying equation (1) by 1.75 and subtracting the result equation from equation (2). This gives,
![1.75x+1.75y=962.5\\\\\\1.75x+2.25y=1153\\1.75x+1.75y=962.5\\(-)\\-------------\\0.5y=190.5\\\\y=\frac{190.5}{0.5}=381](https://tex.z-dn.net/?f=1.75x%2B1.75y%3D962.5%5C%5C%5C%5C%5C%5C1.75x%2B2.25y%3D1153%5C%5C1.75x%2B1.75y%3D962.5%5C%5C%28-%29%5C%5C-------------%5C%5C0.5y%3D190.5%5C%5C%5C%5Cy%3D%5Cfrac%7B190.5%7D%7B0.5%7D%3D381)
So, there were 381 adults at the pool. Now, the number of children is equal to:
![x=550-y=550-381=169](https://tex.z-dn.net/?f=x%3D550-y%3D550-381%3D169)
Therefore, there were 169 children at the pool.
