Danai is decorating her house for Halloween. She puts 12 plastic skulls all around the house. She has 4 broomsticks, 1 for each side of the front and back doors to the house. She puts up 12 spiderwebs around various areas of the house. Danai puts twice as many pumpkins around the house as she put spiderwebs. She also places a large cauldron on the dining room table. If Danai has the budget left to buy 20 more decorations and has 10 left to put up, how many decorations will she put up in all? Give me reasons, before answering the question
Danai places 12 skulls + 4 broomsticks + 12 spiderwebs + 1 cauldron = 29 decorations. She also puts up twice as many pumpkins around the house as she put spiderwebs, 12 x 2 = 24 pumpkins. Danai will also add 20 + 10 decorations to the 29 + 24 decorations already up = 83 total decorations Danai will put up. So the final answer is 83.
