Jack has been driving for the past 9 years. He drives 37,000 miles every four months. How many miles has Jack driven since he started driving?
There are 12/4 = <<12/4=3>>3 four month groups in a year
Jack drives 37,000*3 = <<37000*3=111000>>111,000 miles in a year.
Jack has driven 111,000*9 = <<111000*9=999000>>999,000 miles since he has started driving.
#### 999,000
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:

Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby?Jenny is older than Charlie by 5 years who is older than Bobby by 3 years, so Jenny is older than Bobby by 5+3 = <<8=8>>8 years
Jenny will be twice as old as Bobby when he is 8*2 = 16 years old
Jenny is 5 years older than Charlie so when Jenny is 16, Charlie will be 16-5 = 11 years old

To get ready for the new school year, Mary brought her two kids shopping. She bought her son James, a coat for $40 and two pairs of jeans. She bought his sister Jamie, a pair of shoes for $30. The total cost of the items was $110. If the two pairs of jeans for James cost the same price, how much did one pair of jeans cost?The total spent on both pairs of jeans was $110 - $40 - $30 = $<<110-40-30=40>>40.
One pair of jeans would cost $40 / 2 = $<<40/2=20>>20.
