[Question]: Jame gets 20 singing lessons. He gets the first lesson free and after the first 10 paid lessons he only needs to pay for every other lesson. Each lesson is $5. His uncle pays for half. How much does James pay?
[Answer]: The first lesson is free. The lessons 2 to 11 cost 10 * $5 = $50. He then had 9 remaining lessons where he had to pay for every other one. So he pays for lessons 13,15,17&19 = 4 lessons. Those lessons cost 4 * $5 = $20. So in total, the cost was $50 + $20 = $70. So he paid $70 / 2 = $35.
So the answer is 35.

[Question]: Miss Walter has 50 gold stickers. She also has twice as many silver stickers as gold stickers, and 20 fewer bronze stickers than silver stickers. She wants to give the same number of stickers to each of her 5 students. How many stickers will each student receive?
[Answer]:
She has 50 x 2 = 100 silver stickers. And she also has 100 - 20 = 80 bronze stickers. So, Miss Walter has a total of 50 + 100 + 80 = 230 stickers. Therefore, her 5 students will have 230 / 5 = 46 stickers each.
So the answer is 46.
