Answer:

$284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Step-by-step explanation:

Firstly, to calculate the portions each class should have, we should find the proportion each class takes up.

Hence, let's say A represents Mr. Aceves' class, B represents Mrs. Baca's class, and C represents Mr. Canyon's class.

The total number of box tops collected would be 3760 + 2301 + 1855 = 7916 box tops.

Therefore, the total proportions would be:

A = \frac{3760}{7916}

B = \frac{2301}{7916}

C = \frac{1855}{7916}

Hence, we can finally multiply these proportions with the total prize to find the appropriate division:

Mr. Aceves' class gets \frac{3760}{7916} \cdot 600 \approx 284.99.

Mrs. Baca's class gets \frac{2301}{7916} \cdot 600 \approx 174.41.

And Mr. Canyon's class gets \frac{1855}{7916} \cdot 600 \approx 140.60.

Finally, $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Hope this helped!
