Answer the following question.
Roman the Tavernmaster has $20 worth of gold coins. He sells 3 gold coins to Dorothy. After she pays him, he has $12. How many gold coins does Roman have left?
Step-by-step reasoning process: Dorothy paid $12 for 3 gold coins so each gold coin is worth $12 / 3 = $4. The Tavern master originally had $20 worth of gold coins which is $20 / $4 = 5 gold coins. He gave 3 out of 5 gold coins to Dorothy so he now has 5 - 3 = 2 gold coins left.
The answer is 2.

Answer the following question.
In a 5-day Fishing competition, Jackson was able to reel a total of 6 fishes per day, Jonah was able to reel 4 fishes per day and George was able to reel 8 fishes per day. How many fishes were they able to catch throughout the competition if they are on the same team?
Step-by-step reasoning process: Jackson gets a total of 6x5 = 30 fishes after the competition. Jonah gets 4x5 = 20 fishes after the competition. And George was able to get 8x5 = 40 fishes after the competition. Therefore the total fishes they were able to get for their team is 30 + 20 + 40 = 90.
The answer is 90.

Answer the following question.
A cleaning company produces two sanitizer sprays. One spray kills 50% of germs, and another spray kills 25% of germs. However, 5% of the germs they kill are the same ones. What percentage of germs would be left after using both sanitizer sprays together?
Step-by-step reasoning process: After the first spray kills 50% of germs, there will be 100 - 50 = 50% left. The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = 20%. After the second spray kills 20% of the remaining germs, there will be 50 - 20 = 30% left.
The answer is 30.

Answer the following question.
Bella bought stamps at the post office. Some of the stamps had a snowflake design, some had a truck design, and some had a rose design. Bella bought 11 snowflake stamps. She bought 9 more truck stamps than snowflake stamps, and 13 fewer rose stamps than truck stamps. How many stamps did Bella buy in all?
Step-by-step reasoning process: The number of truck stamps is 11 + 9 = 20. The number of rose stamps is 20 − 13 = 7. Bella bought 11 + 20 + 7 = 38 stamps in all.
The answer is 38.
