Let's determine how much of the \[tex]$300,000 in school funds should go to North Middle. We will distribute the funds proportionally based on the number of kids in each school.
1. Calculate the total number of kids across all four schools:
We add up the number of kids in each school:
\[
400 + 650 + 500 + 450 = 2000
\]
2. Determine the proportion of kids at North Middle relative to the total number of kids:
The proportion is calculated by dividing the number of kids at North Middle by the total number of kids:
\[
\text{Proportion of kids at North Middle} = \frac{400}{2000} = 0.2
\]
3. Calculate the funding for North Middle based on the proportion:
We allocate the funds proportionally by multiplying the total funds by the proportion of kids at North Middle:
\[
\text{Funding for North Middle} = 0.2 \times 300,000 = 60,000
\]
Hence, the amount of funding that should go to North Middle is:
\[
\boxed{60,000}
\]
Therefore, the correct answer is (B) \$[/tex]60,000.
