Question

take 25% off the original. now take off an additional 10% and calculate the new sales cost of this item. what is your total percent of savings?​

Answer 1

x = original price, or 100%

if we take off 25% from 100% what's left is 75%, that's the discounted price.

let's then take 10% of that.

`\bf \begin{array}ll \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{75\% of`

`\bf \stackrel{\textit{changing that to percent format}}{0.675\cdot 100\implies 67.5\%}`
