A dealer has a lot that can hold 30 vehicles. In this lot, there are two available models, A and B. The dealer normally sells at
least twice as many model A cars as model B cars. If the dealer makes a profit of $1300 on model A cars and $1700 on model B cars, how many of each car should the dealer have in the lot given that the total profit for the sale of both cars is $43,000?
