The greatest common factor shared by 32 and 44 is 4. This is factored out as follows: 4(8 + 11) = 4(8 + 11), which appears strange to me, but that's how most textbooks illustrate the factoring process.
Determining the answer here is quite straightforward. Ella has a total of $2.16, and we need to ascertain the cost per piece of gum.
It is known that if the gum cost one cent less, she would have acquired three more pieces.
Currently, with 8 pieces priced at 27 cents each, a reduced price would allow her to have 8.64 pieces. This outcome, even after rounding, is incorrect as it does not yield 11.
For 9 pieces at 24 cents each, a cheaper price would mean she could have 9.39 pieces, which still does not round to 12, indicating it's incorrect.
At 16 pieces costing 13.5 cents each, at one cent less, she would acquire 17.28 pieces, which also confirms it's wrong because rounding does not yield 19.
When purchasing 24 pieces at 9 cents each, with the cheaper price, she could buy 27 pieces, which is valid since 27-24 equals 3.
Therefore, the correct answer is D) 24
Detailed breakdown:
For beef, we calculate 12 * 8 (since 25 * 8 gives 200)
Thus, beef totals = 96
For chicken, we find 8 * 8 (again, because 25 * 8 equals 200)
Hence, chicken totals = 64
For pasta, the calculation is 5 * 8 (as 25 * 8 = 200)
Thus, pasta totals = 40
Conclusion- C] There are 32 extra students preferring beef over those who choose chicken
7 hours 12 minutes

--------------------------sum
Total: 19 hours 111 minutes, which converts to (19 × 60) + 111 = 1140 + 111 = 1251 minutes
Calculate average time by dividing by 3: 1251 / 3 = 417 minutes, equivalent to 6 hours 57 minutes, which is the average delivery duration.
