Alicia had a wonderful birthday party where she got lots of presents. 10 of the presents were in small boxes. 12 of the presents were in medium boxes. A third of all the presents she is given are in large boxes. How many presents did Alicia get for her birthday? Let's be accurate as possible.
Alicia got 10 small boxed presents + 12 medium boxed presents = 22 presents. A third of all the presents Alicia gets are in large boxes, 22 / 2 = 11 is half of the presents we know Alicia got. 11 x 3 = 33 presents Alicia got on her birthday.
The answer: 33.
