Step 1

Use the concept of percentage decrease.

Step 2

New price = $458.81

Original price = x

Percentage decrease = 27%

Step 3

Find the decrease

[tex]\begin{gathered} Decrease\text{ = 27\% of x} \\ \\ =\text{ 0.27x} \end{gathered}[/tex]

Step 4

New price = Original price - Decrease

[tex]\begin{gathered} 458.81\text{ = x - 0.27x} \\ \\ 458.81\text{ = 0.73x} \end{gathered}[/tex]

Step 5

Divide both sides by 0.73

[tex]\begin{gathered} 458.81\text{ = 0.73x} \\ \\ x\text{ = }\frac{458.81}{0.73} \\ \\ x\text{ = 628.506849315} \end{gathered}[/tex]
