Solution:
Given:
[tex]\begin{gathered} Cost\text{ price}=320\text{ euros} \\ Age=35years \\ Discount=35\text{ \%} \end{gathered}[/tex]Thus, the buyer will pay;
[tex]\begin{gathered} 100-35=65\text{ \%} \\ 65\text{ \% of the cost price}=\frac{65}{100}\times320 \\ =\text{ \$}208 \end{gathered}[/tex]Therefore, the 35-year-old buyer will pay $208 for the glass frame.
