Question

A freezer was sold during a clearance sale for​ $387.50. If the freezer was sold at a discount of 50/3%​, what was the list​ price?

Answer 1

so.. if we take 387.50 as the 100%,
then we shave off from it, (50/3)%
what hmmm do we end up with?


`\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 387.50&100\\ x&100-(50)/(3) \end{array}\qquad \implies \cfrac{387.50}{x}=\cfrac{100}{100-(50)/(3)} \\\\\\\\ \cfrac{387.50}{x}=\cfrac{(100)/(1)}{(250)/(3)}\implies \cfrac{387.50}{x}=\cfrac{100}{1}\cdot \cfrac{3}{250}\implies \cfrac{387.50}{x}=\cfrac{300}{250}`

solve for "x"
