Step-by-step explanation:
Since the price has been reduced by 20%, then 80% if the price is equal to 16€> Solve the equation below
Let x be the shoe price,
[tex]x - shoe price[/tex]
[tex]80\% = \frac{80}{100} = 0.8[/tex]
[tex]0.8 \times x = 16 \: \: \: \: \: / \div 0.8[/tex]
[tex]x = \frac{16}{0.8} = 20[/tex]
Therefore, the cost of shoes before the discount is 20€.
