Answer

The price of the camcorder before the reduction was $\$780$

Work Step by Step

$\textbf{The problem to be solved is:}$ After a $40\%$ price reduction, you purchase a camcorder for $\$468$. What was the camcorder's price before the reduction? Let $x$ be the price before the reduction. Since the price reduction was a $40\%$, it can be expressed as $0.4x$ Write an equation that represents the problem given: $x-0.4x=468$ Simplify the left side of the equation: $0.6x=468$ Take $0.6$ to divide the right side: $x=\dfrac{468}{0.6}$ $x=780$ The price of the camcorder before the reduction was $\$780$
