1. Ok so first I would find 22% of 212,000 to do that you do: 22 divide 100 = 0.22

2. Now that you’ve turned 22% into a decimal as 0.22 you find what 22% of 212,000 is like so: 0.22x212,000 =46,640


3. Now that you have to reduce 212,000 but 22% to do this you just subtract: 212,000-46,640= 165,360

They would purchase the house for $165,360
