Answer:
The final cost for him is;
[tex]\text{ \$154.44}[/tex]Explanation:
Given that the ipod costs $220;
[tex]C=\text{ \$220}[/tex]The store gives a 35% discount, which means he will only pay 65% of the original cost;
[tex]100\text{\%- 35\% = 65\%}[/tex]The store price is;
[tex]\begin{gathered} P=\text{ 65\% of \$220} \\ P=\frac{65}{100}\times\text{ \$220} \\ P=\text{ \$143} \end{gathered}[/tex]Also he will need to pay additional 8% sales tax on the discounted price P;
[tex]\begin{gathered} t=8\text{\% of P} \\ t=8\text{\% of \$143} \\ t=\frac{8}{100}\times\text{ \$143} \\ t=\text{ \$11.44} \end{gathered}[/tex]The final cost he need to pay is the sum of the discounted price and the sales tax;
[tex]\begin{gathered} F=P+t \\ F=\text{ \$143 + \$11.44} \\ F=\text{ \$154.44} \end{gathered}[/tex]Therefore, the final cost for him is;
[tex]\text{ \$154.44}[/tex]
