Question

please help me with this problem Jess paid $325 for a snowboard. He bought the board on sale for 15% off the regular price. What was the regular price of the snowboard?

Answer 1

Let it be x the regular price. Now, we can use a rule of three to solve the exercise.

`\begin{gathered} x\rightarrow100\% \\ \text{\$}325\rightarrow85\% \\ \text{ Because} \\ 100\%-15\%=85\% \end{gathered}`

Now, we have:

`\begin{gathered} x=\frac{\text{\$}325\cdot100\%}{85\%} \\ x=\frac{\text{\$}325\cdot100}{85} \\ x=\text{\$}(325\cdot100)/(85) \\ x=\text{\$}(32500)/(85) \\ x=\text{\$}382.35 \end{gathered}`

Therefore, the regular price of the snowboard was $382.35.
