Violet has 3 more than twice as many nails as Tickletoe. If Violet has 27 nails, how many nails do they have together? Give the rationale and then the answer.
Let's think step by step. Violet has 27 - 3 = 24 nails, twice the number of nails that Tickletoe has. Therefore, Tickletoe has 1 / 2 * 24 = 12 nails. Together, Tickletoe and Violet have 12 + 27 = 39 nails.. The answer is: 39.

Jenna is buying concert tickets for her group of five friends. She's able to get two of the tickets from the concert website for $50 each before they sell out. A scalper offers to sell her two more tickets for 240% of the normal price, but Jenna convinces him to give her $10 off that total payment. Finally, one of her friends gets a discounted ticket through her job for 60% of the normal price. How much do Jenna's friends pay for their tickets in total? Give the rationale and then the answer.
Let's think step by step. First calculate the price of the two normally priced tickets by multiplying the price and the quantity: $50 * 2 = $100. Then calculate the scalper's initial asking price by multiplying the normal cost of two tickets by 240%: $100 * 2.4 = $240. Then subtract the $10 discount Jenna negotiated: $240 - $10 = $230. Now calculate the price of the discounted ticket Jenna's friend gets through her job by multiplying the normal ticket price by 60%: $50 * .6 = $30. Finally, add up the price of all the tickets to find the total: $100 + $230 + $30 = $360.. The answer is: 360.

Toby is counting goldfish in the local pond. He knows that only 25% of goldfish are at the surface and the rest are too deep below the surface to be able to see. If he counts 15 goldfish, how many are below the surface? Give the rationale and then the answer.
Let's think step by step. There are 60 goldfish because 15 / .25 = 60. 75% of the fish are below the surface because 100 - 25 = 75. There are 45 goldfish below the surface because 60 x .75 = 45.. The answer is: 45.
