Tim bought a pair of running shoes marked 25% down at a price of $60
The formula to find the discount of an item on sale is
[tex]\text{ \% discount =}\frac{Discount\text{ price}}{\text{Original price}}\times100\text{\%}[/tex]
Where
[tex]\begin{gathered} \text{Discount price = \$60} \\ \text{\% discount = 25\%} \end{gathered}[/tex]
Let k represent the original price
Substitute the values into the formula above
[tex]\begin{gathered} 25=\frac{60}{k}\times100 \\ \text{Crossmultiply} \\ 25\times k=60\times100 \\ 25k=6000 \\ \text{Divide both sides by 25} \\ \frac{25k}{25}=\frac{6000}{25} \\ k=\text{\$240} \end{gathered}[/tex]
Hence, the original price, k, of the pair of Zeus running shoes is $240
