Question: Susie babysits every day for 3 hours a day at the rate of $10 per hour. She spent 3/10 of the money she earned from last week to buy a make-up set. She then spent 2/5 of her money on her skincare products. How much is left from her earnings last week, in dollars?
Answer: Step-by-step reasoning process: Susie earned $10 x 3 = $30 per day. Last week, she earned a total of $30 x 7 = $210. She spent $210 x 3 / 10 = $63 on make - up. While she spent $210 x 2 / 5 = $84 on her skincare products. Thus, she spent a total of $63 + $84 = $147 from her earnings. Therefore, Susie is left with $210 - $147 = $63 from her earnings last week.
So the answer is 63.

Question: There are 10 students in a class. The average age of 9 of them is 8 years. By how many years will this average increase if the tenth student is (quite strangely) 28 years old?
Answer: Step-by-step reasoning process: 9 students have an average age of 8 years so the sum of their ages is 9 * 8 = 72 years. A tenth student who is 28 years old will make the sum 72 + 28 = 100 years. The new average age will be 100 / 10 = 10 years. This is 10 - 8 = 2 years higher than the previous average.
So the answer is 2.

Question: The average temperature in Orlando in a particular week was 60 degrees. If the temperature on each of the first 3 days in that week was 40, and the temperature for Thursday and Friday was 80 degrees each, calculate the total temperature of the remaining days of that week.
Answer: Step-by-step reasoning process: If the average temperature of Orlando for the week was 60, then the total temperature for the week was 7 * 60 = 420 degrees. For the first three days of that week, the temperature was 40 degrees each day, totaling 3 * 40 = 120 degrees in the three days. The temperature for Thursday and Friday was 80 degrees each, a total of 80 * 2 = 160 degrees. The temperature of Orlando for the first five days was 160 + 120 = 280 degrees. The temperature for the remaining two days is 420 - 280 = 140 degrees.
So the answer is 140.

Question: Jean has three times as much money as Jane. They have a combined total of $76. How much money does Jean have?
Answer:
Step-by-step reasoning process: Let's assume the total amount of money that Jane has is m. Since Jean has 3 times as much money as Jane, he has 3 * m = 3m. Combined, Jean and Jane have a total of m + 3m = $76. This evaluates to 4m = $76. The total amount of money that Jane has, represented by m, is m = $76 / 4. Jane has m = $19. Since Jean has three times as much money as Jane, Jean has 3 * $19 = $57.
So the answer is 57.
