A car dealer purchased 2 cars, one for $1500 and the other for $20000, He then sold the first car at a loss of 14% and the second car for a profit of 15%. Find the dealer¡¯s profit for the whole transaction and express the answer as a percentage of his total cost.

I assume you meant 15000, not 1500.
cost = 15000 + 20000 = 35000
sales: 15000*.86 + 20000*1.15 = 35900
profit = 900 = 2.57% of 35000
