Janette went camping for 5 days. She brought along 40 pieces of beef jerky. She wants to ration it out so that she can eat 1 for breakfast, 1 for lunch, and 2 for dinner each day. When she returns from the trip, she plans on giving half of the remaining pieces to her brother. How many pieces of beef jerky will she have left once she does this?
Each day she eats a total of 1 + 1 + 2 = <<1+1+2=4>>4 pieces of jerky.
For the entire trip, she will consume a total of 4 * 5 = <<4*5=20>>20 pieces of jerky.
She gives half to her brother, which will leave her a total of 20 / 2 = <<20/2=10>>10 pieces of jerky.

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:

In a certain school, 2/3 of the male students like to play basketball, but only 1/5 of the female students like to play basketball. What percent of the population of the school do not like to play basketball if the ratio of the male to female students is 3:2 and there are 1000 students?The students are divided into 3 + 2 = <<3+2=5>>5 parts where 3 parts are for males and 2 parts are for females.
Each part represents 1000/5 = <<1000/5=200>>200 students.
So, there are 3 x 200 = <<3*200=600>>600 males.
And there are 2 x 200 = <<2*200=400>>400 females.
Hence, 600 x 2/3 = 400 males play basketball.
And 400 x 1/5 = <<400*1/5=80>>80 females play basketball.
A total of 400 + 80 = <<400+80=480>>480 students play basketball.
Therefore, 1000 - 480 = <<1000-480=520>>520 do not like to play basketball.
The percentage of the school that do not like to play basketball is 520/1000 * 100 = <<520/1000*100=52>>52

For a wedding, chairs were arranged in 7 rows with 12 chairs in each row. Some people arrived late and grabbed 11 extra chairs, placing them at the back. How many chairs were there altogether?At first, there were 7*12=<<7*12=84>>84 chairs.
Later, there were 84+11=<<84+11=95>>95 chairs altogether.
#### 95[END]

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

Janette went camping for 5 days. She brought along 40 pieces of beef jerky. She wants to ration it out so that she can eat 1 for breakfast, 1 for lunch, and 2 for dinner each day. When she returns from the trip, she plans on giving half of the remaining pieces to her brother. How many pieces of beef jerky will she have left once she does this?

### Response:
Each day she eats a total of 1 + 1 + 2 = <<1+1+2=4>>4 pieces of jerky.
For the entire trip, she will consume a total of 4 * 5 = <<4*5=20>>20 pieces of jerky.
She gives half to her brother, which will leave her a total of 20 / 2 = <<20/2=10>>10 pieces of jerky.
