 
 <prompt> Tobias na tractor salesman. Im salary dey based on di number of tractors wey e sell. For every red tractor wey e sell, e dey collect 10% of di sales price for each tractor. For every green tractor wey e sell, e dey collect 20% of di sales price for each tractor. Dis week, e sell 2 red tractors and 3 green tractors. Di price of one red tractor na $20,000. Dis week, Tobias salary na $7000. Wetin be di full price of one green tractor, in dollars? <response>: For red tractors, 10% of the sales price na 10/100*$20,000 = $2000.
By selling two red tractors, he make 2*$2000 = $4000.
So, out of the $7000 wey dem pay am this week, $7000-$4000 = $3000 na from sales of green tractors.
And since he sell three green tractors, the commission for one green tractor na $3000/3=$1000,
If $1000 na 20% of the full price, then the full price for one green tractor na (100/20)*$1000 = $5000.

The answer go be 5,000.
