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

### Instruction:
An electronic shop offers smartphones for $300 each, personal computers for $500 more than smartphones, and advanced tablets for the sum of the prices of a smartphone and personal computer. How much do you have to pay to buy one of each of the three mentioned products?

### Response:
A personal computer costs $300 + $500 = $<<300+500=800>>800.
An advanced tablet would cost the sum of the prices of a smartphone and personal computer, so it would cost $300 + $800 = $<<300+800=1100>>1100.
To buy each of these products, you would have to pay $300 + $800 + $1100 = $<<300+800+1100=2200>>2200.
