48

anonymous · Answer

if he buys 3 dozens (3*12=36donuts) he won't have enough donuts, but if he buys 4 (4*12=48) he'll have 48, which is 3 more, but enough all the people.

anonymous · Answer

One dozen is twelve, so the lowest multiple of 12 that is at least 45 is 48; hence, 12 * 4, so four boxes.

$$45 \le 12x \rightarrow x \ge 3.75 \rightarrow x = 4$$
