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?
The first lesson is free.
The lessons 2 to 11 cost 10*$5=$<<10*5=50>>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*$5=$<<4*5=20>>20.
So in total, the cost was $50+$20=$<<50+20=70>>70.
So he paid $70/2=$<<70/2=35>>35.

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

A cattle breeder owns 52 dairy cows. Each cow gives 1000 oz of milk per day. Calculate the amount of milk produced per week by the cows.Per day, the amount of milk produced is 1000*52 = <<1000*52=52000>>52000 oz.
Per week, the amount of milk produced is 52000*7 = <<52000*7=364000>>364000 oz.
#### 364000[END]

The capacity of Karson's home library is 400 books. If he currently has 120 books, how many more books does he have to buy to make his library 90% full?When 90% full, Karson's library holds 90/100*400 = <<90/100*400=360>>360 books.
If he has 120 books in the library now, he needs to buy 360-120 = <<360-120=240>>240 books to make his library 90% full.
#### 240[END]

Now, solve this next question in the style of the above examples:
