• $\left[\left(20\ -\ 8\right)\ \div\ 4\right]\ +5$

Marcus bought a coil of landscape edging to put around a flower bed.

 * One coil has 162 ft of landscape edging.
* Each section of the edging is 6 ft long and costs $13.

If he uses the entire coil, which equation can Marcus use to find c, the cost of the sections of edging he needs for the flower bed.

•  $162\ x\ \left(13\ x\ 6\right)\ =\ c$  

•  $162\ \div\ \left(13\ x\ 6\right)\ =\ c$  

•  $\left(162\ \div\ 6\right)\ x\ 13\ =\ c$  

•  $162\ x\ \left(13\ +\ 6\right)\ =\ c$
