Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A normal lemon tree produces 60 lemons per year.  Jim has specially engineered lemon trees that produce 50% more lemons per year.  He has a grove that is 50 trees by 30 trees.  How many lemons does he produce in 5 years?

### Response:
Each tree produces 60 * 150/100 = <<60*150/100=90>>90 lemons per year.
There are 50 * 30 = <<50*30=1500>>1500 trees.
So in 5 years he produces 1500 * 90 * 5 = $<<1500*90*5=675000>>675000 lemons.
#### 675000
