Answer the following question.
Arabella is a dance student learning three new steps this session. Her instructor has her spend thirty minutes on learning the first step. The second step she masters in half the time. The third step is more complex, so it takes her as long as both the other steps to learn. How many minutes did she spend learning the three steps?
Step-by-step reasoning process: Arabella spent 30 / 2 = 15 minutes on the second step. She took 30 + 15 = 45 minutes to learn the third step. Therefore, Arabella spent 30 + 15 + 45 = 90 minutes learning all three steps.
The answer is 90.

Answer the following question.
Julia collects old watches. She owns 20 silver watches, and three times as many bronze watches. She decided to buy gold watches to add to her collection, a number that represents 10% of all the watches she owns. How many watches does Julia own after this purchase?
Step-by-step reasoning process: Julia owns 3 * 20 = 60 bronze watches. 60 + 20 = 80 total silver and bronze watches. 10% of all Julia's watches is 80 * 10 / 100 = 8 watches, and she decided to buy so many gold watches. So in total Julia is in possession of 20 + 60 + 8 = 88 watches.
The answer is 88.

Answer the following question.
Chloe bought chocolate-dipped strawberries at $50 a dozen. She then sold them for $30 for half a dozen during the Mother's Day celebration. How much is Chloe's profit if she sold 50 dozens?
Step-by-step reasoning process: If Chloe bought it for $50 per dozen, then half a dozen cost her $50 / 2 = $25. This means that she has $30 - $25 = $5 profit per half a dozen of chocolate - dipped strawberries. If Chloe sold 50 dozens, then she was able to sell 50 / 1 / 2 = 100 half a dozen chocolate - dipped strawberries. Hence, her profit is $5 x 100 = $500.
The answer is 500.

Answer the following question.
James has 3 gallons of milk. He drank 13 ounces of the milk. If there are 128 ounces in a gallon, how many ounces of milk does James have left?
Step-by-step reasoning process: First find out how many ounces of milk James had to begin with by multiplying the number of gallons by the number of ounces per gallon: 3 gallons * 128 ounces / gallon = 384 oz. Now subtract the 13 ounces James drank from the initial amount of milk: 384 oz - 13 oz = 371 oz.
The answer is 371.
