Quinn catches twice the amount of frogs as Alster who caught 2. Bret catches three times the amount of frogs as Quinn. How many frogs did Bret catch? Give the rationale and then the answer.
Let's think step by step. Quinn catches twice the amount as Alster, who caught 2 frogs so Quinn caught 2 * 2 = 4 frogs. Bret catches three times the amount as Quinn who caught 4 frogs so Bret caught 3 * 4 = 12 frogs.. The answer is: 12.

Hannah brought $30 to the county fair. She spent half of it on rides and another $5 on dessert. How much, in dollars, is left? Give the rationale and then the answer.
Let's think step by step. She spent $30 / 2 = $15 on rides. She spent a total of $15 + $5 = $20 including dessert. She has $30 - $20 = $10 left.. The answer is: 10.

Stephanie is decorating 24 cupcakes for a birthday party, but she needs more candles. She currently has a total of 30 candles. She wants to decorate half of the cupcakes with 1 candle each and the other half of the cupcakes with 2 candles each. How many additional candles does Stephanie need to complete the cupcakes? Give the rationale and then the answer.
Let's think step by step. 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 is: 6.
