Question

A new house was bought for $263,000. Five years later, the house sold for $473,400. What percent of the original price was the increase

Answer 1

well, the difference is 473400-263000 = 210400.

Now, if we take 263000(origin amount) to be the 100%, what's 210400 off of it in percentage?

`\begin{array}{ccll} Amount&\%\\ \cline{1-2} 263000 & 100\\ 210400& p \end{array} \implies \cfrac{263000}{210400}~~=~~\cfrac{100}{p} \\\\\\ \cfrac{5}{4} ~~=~~ \cfrac{100}{p}\implies 5p=400\implies p=\cfrac{400}{5}\implies p=80`
