Part A:
The best equation to use to estimate the number of hats, \( h \), each shelter will receive is:
1,600 ÷ 4 = h
This is because you want to divide the total number of hats (1,596, which can be rounded to 1,600 for estimation purposes) by the number of shelters (4) to find out how many hats each shelter will receive.
Part B:
To find the answer to how many hats each shelter will receive, you can use the equation you selected.
Calculating it:
\[ 1,600 ÷ 4 = 400 \]
So, you can complete the sentence:
Each shelter will receive about 400 hats.
