Final answer:
The student's question is about calculating the number of canned goods collected in September by subtracting the number collected in August from the total collected in both months. The answer is that 6,872 canned goods were collected in September.
Step-by-step explanation:
Joni's community center collected a total of 15,128 canned goods in August and September. We know the number of canned goods collected in August, which is 8,256. What we need to find out is the number of canned goods, c, collected in September.
To find out the amount collected in September, we subtract the number of canned goods collected in August from the total number of canned goods collected in both months. This can be represented by the equation:
c = 15,128 - 8,256.
By calculating the difference, we find out the number of canned goods collected in September:
c = 6,872.
Therefore, Joni's community center collected 6,872 canned goods in September.
