(5) Relaciona cada tabla con su ecuación. \( \begin{array}{llll}x & 5 & -10 & y=\frac{-x+1}{4} \\ y & 2 & -1 & \\ x & 4 & 8 & y=0.2 x+1 \\ y & -5 & -8 & \\ \text { Tabla } 3.26 & \\ x & 5 & -3 & y=-\frac{3 x}{4}-2\end{array} \)

On donne \( u_{0}=-8 \) et \( r=\frac{1}{2} \) Calculer \( u_{0} \) et \( S_{w} \)

7. If by selling a wristwatch for \( ₹ 150 \), a person loses \( 5 \% \). For what amount should it be sold \( s \) profit of \( 20 \% \) ? A grocer buys eggs at 10 for \( ₹ 8 \) and sells at 8 for \( ₹ 10 \). Find his profit or loss per cent. A washing machine was sold at a profit of \( 7 \% \). If it had been sold at a profit of \( 10 \% \), the pre ₹ 770 more What is its CP?
