Question

List the percent decrease for each of the following A year old $30,000 Subaru selling for $24,500

Answer 1

well, the decrease is really 30000 - 24500 = 5500.

now, if we take the 30000 to be the 100%, what is 5500 off of it in percentage?

`\begin{array}{ccll} a&b\\ \cline{1-2} 30000 & 100\\ 5500& x \end{array} \implies \cfrac{30000}{5500}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{ 60 }{ 11 } ~~=~~ \cfrac{ 100 }{ x }\implies 60x=1100\implies x=\cfrac{1100}{60}\implies x=\cfrac{55}{3}\implies x=18(1)/(3)`
