Given that:
Total cost for three CD = $36
Number of CD = 3
To find:
The expression that will represent the cost of one CD.
Solution:
We know that formula, to find the cost of each unit.
[tex]\text{Cost of each unit }=\dfrac{\text{Total cost}}{\text{Number of units}}[/tex]
Using this formula, we get
[tex]\text{Cost of each CD}=\dfrac{\text{Total cost for three CD}}{\text{Number of CDs}}[/tex]
[tex]\text{Cost of each CD}=\dfrac{36}{3}[/tex]
The required expression for cost of one CD is [tex]\dfrac{36}{3}[/tex].
Therefore, the correct option is C.
