Question

A gaming console originally costs $399, but it is 15% off for the holidays. What amount is the discount?

Answer 1

To find the discount we can use the rule of three:

`\begin{gathered} 399\rightarrow100 \\ x\rightarrow15 \end{gathered}`

Then:

`x=(15\cdot399)/(100)=59.85`

Therefore the discount was $59.85.
