Skyler is a composer. He wrote 25 hit songs that made it on the top 10 charts; ten more songs that made it on the top 100 charts than the hit songs; 5 fewer songs than the hit songs that were never released. How many songs did Skyler write in all? Give the rationale and then the answer.
Let's think step by step. Skyler wrote 25 + 10 = 35 songs that made it on the top 100. He wrote 25 - 5 = 20 songs that were never released. So, Skyler wrote a total of 25 + 35 + 20 = 80 songs.. The answer is: 80.

Pima invested $400 in Ethereum. In the first week, it gained 25% in value. In the second week, it gained an additional 50% on top of the previous gain. How much is her investment worth now? Give the rationale and then the answer.
Let's think step by step. For the first week, her investment gain is $400 * 25% = $100. This leaves her investment with a value of $400 + $100 = $500. For the second week, her investment increased by $500 * 50% = $250. Pima's investment in Ethereum is now worth a total of $500 + $250 = $750.. The answer is: 750.
