Question

The price of a new car was £12,500

It is reduced to £11,625

Work out the percentage reduction.

Answer 1

Answer: El porcentaje de reducción exacto es de: 7%, con esto el precio de descuento es de €875.

Answer 2

well, the reduction in value is £12500 - £11625 = £875.

if we take 12500 to be the 100%, what is 875 off of it in percentage?

`\begin{array}{ccll} amount&\%\\ \cline{1-2} 12500 & 100\\ 875& x \end{array} \implies \cfrac{12500}{875}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{100}{7}=\cfrac{100}{x}\implies 100x=700\implies x=\cfrac{700}{100}\implies x=7`
