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

### 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:
 Bei ya kompyuta ya kibinafsi ni $300 + $500 = $<<300+500=800>>800.
Bei ya kibao cha kisasa ingekuwa $300 + $800 = $<<300+800=1100>>1100.
Hivyo, kununua kila moja ya bidhaa hizi, unapaswa kulipa $300 + $800 + $1100 = $<<300+800+1100=2200>>2200.
