Let X represent the amount of taxes on the 180,000 dollar home. Now, let’s set up a proportion in which one ratio compares the home values, and the other ratio compares the corresponding taxes. So, $\frac{150000}{180000}$ = $\frac{1900}{X}$ To solve this equation, we equate the cross products. 150000 $\times$ X = 180000 $\times$ 1900 We divide both sides by 10000 to simplify: 15 $\times$ X = 18 $\times$ 1900 15X = 34200 Divide both sides by 15. X = 2280 There are 2280 dollars of taxes on a home valued at 180,000 dollars.
