When you purchase donuts, they come in boxes of 12, so 24 donuts take 2 boxes.All donuts need to be in a box, so if you buy 13 donuts, you'll get 2 boxes with 12 in the first box and 1 in the second.If the integer variable numberOfDonuts contains the positive number of donuts purchased, which of the following will correctly give the number of boxes needed?
A)int numberOfBoxes = (numberOfDonuts + 11) / 12;
B)int numberOfBoxes = numberOfDonuts / 12;
C)int numberOfBoxes = 1 + numberOfDonuts / 12;
D)int numberOfBoxes = numberOfDonuts / 12 + numberOfDonuts % 12;

To get the number of boxes needed, we need to divide the total number of donuts by the number of donuts in a single box (12) and round up to the nearest integer. The expression (numberOfDonuts + 11) / 12 achieves this by adding 11 before dividing, which effectively rounds up to the nearest multiple of 12. For example, if we have 20 donuts, (20 + 11) / 12 gives us 2, which is the correct number of boxes needed (1 box with 12 donuts and another box with 8 donuts).
