Question: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
Answer: Step-by-step reasoning process: Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones.
So the answer is 111.

Question: Zoe made a total of $8,000 cleaning pools and babysitting. She babysat Julie three times as often as she babysat Zachary. The number of times she babysat Zachary was 1/5 the number of times she babysat Chloe. If Zoe made $600 babysitting Zachary, how much did she earn from pool cleaning?
Answer: Step-by-step reasoning process: From babysitting Julie, Zoe made 3 * 600 = 1800 dollars, since she made $600 babysitting Zachary and she babysat Julie three times as often. Since she babysat Zachary 1 / 5 as often as she babysat Chloe, she made an additional 5 * 600 = 3000 dollars from babysitting Chloe. All together, the babysitting sessions made Zoe 600 + 1800 + 3000 = 5400 dollars. Subtracting babysitting payments from the total gives 8000 - 5400 = 2600 dollars. Zoe therefore made 2600 dollars cleaning pools.
So the answer is 2600.

Step-by-step reasoning process: Knives 2, 3 & 4 will cost $4.00 each to sharpen so that’s 3 * 4 = $12.00. Knives 5 - 9 will cost $3.00 each to sharpen so that’s 5 * 3 = $15.00. The first knife will cost $5.00, the next 3 cost $12.00 and the rest cost $15.00 for a total of 5 + 12 + 15 = $32.00.
So the answer is 32.
