Reasoning and answer: Day 1:50. Day 2:50(2) = 100. Day 3:100 + 20 = 120. Day 4:2(50 + 100 + 120) = 540. Total:50 + 100 + 120 + 540 = 810 eggs.

For half of the cupcakes, Stephanie wants to use 1 candle each. Since half of the cupcakes is 24 / 2 and she plans to use 1 candle each for this half of the cupcakes, Stephanie needs (24 / 2) * 1 = 12 candles for this half of the cupcakes. For the other half of the cupcakes, Stephanie wants to use 2 candles. Therefore, she will need (24 / 2) * 2 = 24 candles for this half of the cupcakes. Because Stephanie needs 12 candles for half of the cupcakes and 24 candles for the other half, she needs a total of 12 + 24 = 36 candles. Since Stephanie needs 36 candles to decorate all the cupcakes and she currently has 30 candles, Stephanie needs 36 - 30 = 6 additional candles.
The answer: 6
Reverse engineering the question: Stephanie is decorating 24 cupcakes for a birthday party, but she needs more candles. She currently has a total of 30 candles.

Reasoning and answer: Let t be the price of the small tubs. 3 * 6 + 6 * t = 48. 18 + 6 * t = 48. 6 * t = 48 - 18 = 30. 6t = 30. t = 5 dollars for each small tub.
The answer: 5
