Step-by-step explanation
The percentage of 5 years old that received a full or partial subsidy is given by the following expression:
a.
![\text{Full or }partial\text{ subsidy=}(49+11)/(78)=(60)/(78)=0.77](https://img.qammunity.org/2023/formulas/mathematics/college/3lt9s8zhpbh8mqifjnd4x0podgt9znlsic.png)
b.
No-subsidy:
![No\text{ subsidy=}(18)/(49+11+18)=(18)/(78)=0.23](https://img.qammunity.org/2023/formulas/mathematics/college/7evl1hmf1xiedl8ovw2flcq5qu3lxp31xm.png)
c. 4 years old Full subsidy:
![4\text{ years old full subsidy percentage=}(22)/(26+22+49)=(22)/(97)=0.23](https://img.qammunity.org/2023/formulas/mathematics/college/8hwdwghoeegt0ajlc7yvwgjz0tdc49rjix.png)
d. Percentage of children that are 5 years old:
![=(49+11+18)/(26+40+38+22+38+13+49+11+18)=(78)/(255)=0.3](https://img.qammunity.org/2023/formulas/mathematics/college/h88hur6w6zhg0jt7ndqi1bhv7eco0oip5o.png)
e.
Since the expression of funding is:
Funding = 1530f + 1750p + 1875n
Number of children receiving full subsidy f =
![=(26+22+49)/(26+22+49+40+38+11+38+13+18)=(97)/(255)=0.38](https://img.qammunity.org/2023/formulas/mathematics/college/148t0cu13zntkt1hyt6ycjflxxpa5dpxu0.png)
Number of children receiving partial subsidy=
![=(40+38+11)/(26+22+49+40+38+11+38+13+18)=(89)/(255)=0.35](https://img.qammunity.org/2023/formulas/mathematics/college/yrxc1zlq7ft7xh8d071qdsfh5ie4kryhuv.png)
Number of children receiving no subsidy:
![=(38+13+18)/(26+22+49+40+38+11+38+13+18)=(69)/(255)=0.27](https://img.qammunity.org/2023/formulas/mathematics/college/up313ez8z5r7zlxrdm8uqvcdlrnljmstkf.png)
Thus, f=0.38, p=0.35 and n=0.27
Plugging in into the equation:
![=1530\cdot0.38+1750\cdot0.35+1875\cdot0.27=581.4+612.5+506.25=1700](https://img.qammunity.org/2023/formulas/mathematics/college/hatr2ql4gzpfypyn5t7jyl21caq4zh3rr4.png)
In conclusion, the center's federal funding was of $1,700
