Answer the following question.
James decides to buy himself a new barbell. It cost 30% more than his old $250 barbell. How much did it cost?
Step-by-step reasoning process: It cost 250 * .3 = $75 more than his old barbell. So it cost 250 + 75 = $325.

Answer the following question.
Violet has 3 more than twice as many nails as Tickletoe. If Violet has 27 nails, how many nails do they have together?
Step-by-step reasoning process: Violet has 27 - 3 = 24 nails, twice the number of nails that Tickletoe has. Therefore, Tickletoe has 1 / 2 * 24 = 12 nails. Together, Tickletoe and Violet have 12 + 27 = 39 nails.
The answer is 39.

Answer the following question.
Joe had 200 data points on his dataset. He then added 20% more data points to the dataset. If he reduced the data points by 1/4 of the total data points, calculate the total number of data points the dataset contains.
Step-by-step reasoning process: When Joe added 20% more data points to the dataset, the data points in the dataset increased by 20 / 100 * 200 = 40 data points. The total number of data points increased to 200 + 40 = 240. If he reduced the data points by 1 / 4 of the total data points, the data points reduced by 1 / 4 * 240 = 60. The total number of data points left in the dataset after Joe reduced the data points by 1 / 4 of the total data points is 240 - 60 = 180.
The answer is 180.

Answer the following question.
There are 10 bags with 30 oranges each on a truck. A total of 50 pieces of oranges are rotten. Thirty pieces of oranges will be kept for making orange juice and the rest will be sold. How many pieces of oranges will be sold?
Step-by-step reasoning process: There are a total of 10 x 30 = 300 pieces of oranges in a truck. A total of 50 + 30 = 80 pieces of oranges will not be sold. Thus, 300 - 80 = 220 pieces of oranges will be sold.
The answer is 220.
