The final cost for him is;

Explanation:
Given that the ipod costs $220;
![C=\text{ \$220}](https://tex.z-dn.net/?f=C%3D%5Ctext%7B%20%5C%24220%7D)
The store gives a 35% discount, which means he will only pay 65% of the original cost;
![100\text{\%- 35\% = 65\%}](https://tex.z-dn.net/?f=100%5Ctext%7B%5C%25-%2035%5C%25%20%3D%2065%5C%25%7D)
The store price is;
![\begin{gathered} P=\text{ 65\% of \$220} \\ P=\frac{65}{100}\times\text{ \$220} \\ P=\text{ \$143} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20P%3D%5Ctext%7B%2065%5C%25%20of%20%5C%24220%7D%20%5C%5C%20P%3D%5Cfrac%7B65%7D%7B100%7D%5Ctimes%5Ctext%7B%20%5C%24220%7D%20%5C%5C%20P%3D%5Ctext%7B%20%5C%24143%7D%20%5Cend%7Bgathered%7D)
Also he will need to pay additional 8% sales tax on the discounted price P;
![\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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20t%3D8%5Ctext%7B%5C%25%20of%20P%7D%20%5C%5C%20t%3D8%5Ctext%7B%5C%25%20of%20%5C%24143%7D%20%5C%5C%20t%3D%5Cfrac%7B8%7D%7B100%7D%5Ctimes%5Ctext%7B%20%5C%24143%7D%20%5C%5C%20t%3D%5Ctext%7B%20%5C%2411.44%7D%20%5Cend%7Bgathered%7D)
The final cost he need to pay is the sum of the discounted price and the sales tax;
![\begin{gathered} F=P+t \\ F=\text{ \$143 + \$11.44} \\ F=\text{ \$154.44} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20F%3DP%2Bt%20%5C%5C%20F%3D%5Ctext%7B%20%5C%24143%20%2B%20%5C%2411.44%7D%20%5C%5C%20F%3D%5Ctext%7B%20%5C%24154.44%7D%20%5Cend%7Bgathered%7D)
Therefore, the final cost for him is;

Answer:
4 inches per second
Step-by-step explanation:
Speed = distance/time
Given
Distance = 20 feet
12 inches = 1 foot

Time = 1 minute = 60 secs
Therefore
Speed = 240/60
= 4 inches per second
