Recycled​ CDs, Incorporated, offers a choice of 5 used CDs for ​$27​, with each additional CD costing ​$5. Write a cost function
notka56 [123]

A function assigns the values. The cost of 6 CDs will be $32.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given that the Recycled​ CDs. Incorporated, offers a choice of 5 used CDs for ​$27​, with each additional CD costing ​$5. Therefore, a cost function for purchasing 5 or more CDs, where x represents the number of CDs over 5 can be written as,

C(x) = $27 + $5(x)

Now, if 6 CDs are purchased then the number of CDs that are more than 5 is 1. therefore, the cost of 6 CDs will be,

C(1) = $27 + $5(1)

     = $27 + $5

     = $32

Hence, the cost of 6 CDs will be $32.
