Pat's Pool Supply has three times as many swimming pools as Pat's Ark & Athletic Wear store. If Pat's Ark & Athletic Wear store has 200 pools, how many pools do they have in total?
Step-by-step reasoning process: Since Pat's Ark & Athletic Wear store has 200 pools, Pat's Pool Supply has 3 * 200 = 600 swimming pools. Together, they have 600 + 200 = 800 swimming pools.

Answer the following question.
A survey was conducted by a school to the parents about their children's online class experience. Fifteen percent of the respondents rated Excellent; 60% rated Very Satisfactory; 80% of the remaining respondents rated Satisfactory and the rest rated Needs Improvement. If 120 parents answered the survey, how many of them rated Needs Improvement?
Step-by-step reasoning process: The total percentage of those who rated Excellent or Very Satisfactory is 15% + 60% = 75%. Seventy - five percent of the parents is 120 x 75 / 100 = 90. Hence, 120 - 90 = 30 students rated either Satisfactory or Needs Improvement. A total of 30 x 80 / 100 = 24 parents rated Satisfactory. Therefore, 30 - 24 = 6 parents rated Needs Improvement.
The answer is 6.

Answer the following question.
Joseph had 16 baseball cards. He gave 3/8 of the cards to his brother and 2 cards to his brother. What percentage of the cards is left to Joseph?
Step-by-step reasoning process: Joseph gave 16 x 3 / 8 = 6 cards to his brother. He gave a total of 6 + 2 = 8 cards to his brother and friend. Joseph has 16 - 8 = 8 cards left. This is 8 / 16 x 100% = 50% of his cards.
The answer is 50.

Answer the following question.
Mike wants to buy a new car. He has chosen a red car for $35000. To be able to pay this price, he needs to loan part of the money from the bank, at a rate of 15%. How much money in total will Mike need to pay for the car, if he has to take $20000 from the bank?
Step-by-step reasoning process: The rate of the loan is 15%, which means Mike needs to give the bank an additional 20000 * 15 / 100 = $3000. So the car will cost him 35000 + 3000 = $38000.
The answer is 38000.
