If the dealer sold the first car for a 40% profit, then his cost can be found by x + .40x = 560. Thus his cost 560/1.4 which is $400; thus his profit was $160. By the same token, his loss on the second car was x - .20x = 560. His cost here was x = 560/.8 = 700. His profit here was -$140. His total profit was $160 - $140
which is $20.
