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

### Instruction:
Tobias is a tractor salesman. His salary is based on the number of tractors he sells.  For every red tractor he sells, he gets paid 10% of the sales price for each tractor.  For every green tractor he sells, he gets paid 20% of the sales price for each tractor.  This week, he sold 2 red tractors and 3 green tractors.  The price of a single red tractor is $20,000.  This week, Tobias's salary was $7000.  What is the full price of a single green tractor, in dollars?

### Response:
 Kwa trekta jekundu, 10% ya bei ya mauzo ni 10/100*$20,000 = $2000.
Kwa kuuza trekta mbili jekundu, alipata 2*$2000 = $4000.
Hivyo, kati ya mshahara wa $7000 aliolipwa wiki hii, $7000-$4000 = $3000 ni kutokana na mauzo ya trekta za kijani.
Na kwa kuwa aliuza trekta 3 za kijani, tume ya mauzo ya trekta moja ya kijani ni $3000/3=$1000.
Ikiwa $1000 ni 20% ya bei kamili, basi bei kamili ya trekta ya kijani ni (100/20)*$1000 = $5000.
