Q: Jose owns a swimming pool. He charges $3 for kids and twice that amount for adults. If 8 kids and 10 adults swim in his swimming pool per day, how much money will he earn per week?
A: Jose can earn $3 x 8 = $24 per day for kids. He charges $3 x 2 = $6 per adult. So, he can earn $6 x 10 = $60 per day for adults. Jose earns $60 + $24 = $84 per day for kids and adults. Therefore, he can earn $84 x 7 = $588 per week. The answer is 588.
Question: Brianna started out with a bag of 24 marbles. She lost four marbles through a hole in the bag. Then, she gave away twice as many marbles as she had lost through the hole in the bag. Finally, her dog ate half as many marbles as Brianna had lost through the hole in the bag. How many marbles did Brianna have remaining?
Answer: Brianna gave away twice as many marbles as she had lost, or a total of 2 * 4 = 8 marbles. Her dog ate half as many marbles as Brianna had lost through the hole in the bag, or 4 / 2 = 2 marbles. If she started with 24 marbles, then the number of marbles remaining is 24 - 4 - 8 - 2 = 10 marbles. The answer is 10.
[Question]Judy uses 10 pencils during her 5 day school week. A 30 pack of pencils costs $4. How much will she spend on pencils over 45 days?
[Answer]She uses 2 pencils a day because 10 / 5 = 2. She will use 90 pencils in 45 days because 2 x 45 = 90. She will need 3 packs of pencils because 90 / 30 = 3. She will spend $12 because 3 x 4 = 12. The answer is 12.
Q: The number of students in Kylie's class is 50. In a particular test, ten students scored 90 marks, 15 scored ten marks fewer than the first ten students, and the rest scored 60 marks each. What are the average marks for the whole class?
A: The total marks for the first ten students are 90 * 10 = 900 marks. The 15 students who scored ten marks fewer than the first ten had 90 - 10 = 80 marks each. The total marks for the following 15 students are 15 * 80 = 1200 marks. The total number of students who scored above sixty is 10 + 15 = 25. If 50 students were present in the class, those who scored sixty are 50 - 25 = 25. If 25 students scored 60, then their total marks are 60 * 25 = 1500 marks. The whole class scored a total of 1500 + 1200 + 900 = 3600 marks. The average for the class is 3600 / 50 = 72 marks. The answer is 72.
Question: Noah's bedroom light uses 6 watts per hour. His office light is much brighter so he can see to work and uses three times as much energy. The living room light has a much larger space to cover and has to be more powerful, so it uses four times as much energy as his bedroom light. If Noah leaves all those lights on for two hours, how many watts has he used?
Answer: Noah's bedroom light uses 6 watts per hour, so it would use 2 * 6 = 12 watts in two hours. His office light uses 3 times as many watts as his bedroom light, so it uses 3 * 6 = 18 watts per hour. In two hours, the office light would use 18 * 2 = 36 watts. The living room light uses 4 times as many watts as his bedroom light, so it uses 4 * 6 = 24 watts per hour. In two hours, the living room light would use 24 * 2 = 48 watts. Thus, if Noah leaves all those lights on for two hours, he has used 12 + 36 + 48 = 96 watts. The answer is 96.
