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? Give me reasons, before answering the question
For red tractors, 10% of the sales price is 10 / 100 * $20,000 = $2000. By selling two red tractors, he earned 2 * $2000 = $4000. Thus, of the $7000 salary he was paid this week, $7000 - $4000 = $3000 is from sales of green tractors. And since he sold three green tractors, the commission for the sale of a single green tractor is $3000 / 3 = $1000,. If $1000 is 20% of the full price, then the full price for a green tractor is (100 / 20) * $1000 = $5000. So the final answer is 5000.
