[tex]\begin{gathered} \text{Discounted jacket cost \$64} \\ \text{The discount coupon is reduced by 60\%} \\ \text{The reduced coupon is calulated as } \\ 100\text{ - 60 = 40\%} \\ Applying\text{ the formula} \\ part\text{ = whole x percentage} \\ \text{Let the original price be x} \\ \text{Part = discounted price = \$64} \\ \text{percentage = 40\%} \\ 64\text{ = x }\cdot\text{ }\frac{40}{100} \\ 64\text{ = x }\cdot\text{ 0.4} \\ 64\text{ = 0.4x} \\ \text{Divide both sides by 0.4} \\ \frac{64}{0.4}\text{ = }\frac{0.4x}{0.4} \\ x\text{ = \$160} \\ \text{The original price of the jacket is \$160} \end{gathered}[/tex]
