Question

After a 5% reduction, you purchase a new computer monitor for $270.75. What was the price of the computer monitor before the reduction?

Answer 1

the price was really to be honest "x", which oddly enough is the 100%, but we also know you bought it at 5% off, so you really bought it for 100% - 5% = 95%, and we also know that what you paid was 270.75 bucks, so 270.75 is 95%, what the dickens is the 100% of "x" then?

`\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 270.75& 95 \end{array} \implies \cfrac{x}{270.75}~~=~~\cfrac{100}{95} \\\\\\ 95x=27075\implies x=\cfrac{27075}{95}\implies x=285`
