So I have a math question that says "The next model of a car will be 11.1% less than the current model that costs 51,000. What will be the price decrease in dollars and the price of the next model?" I'm quite stumped on it so any help would be greatly appreciated!

Is δ pmr similar to δ smn ? if so, which postulate or theorem proves these two triangles are similar?
