The the cost of 13 CDs would be $30.
<h3>How to find the Cost Function?</h3>
A cost function is a function of input prices and output quantity whose value is the cost of making that output given those input prices, often applied through the use of the cost curve by companies to minimize cost and maximize production efficiency.
If $20 represents the cost of the 5 used CDs, than your formula would be "20 + 4x" , with x being the amount of extra CDs you purchase.
The number of CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $20 group. Thus;
26 + 4(13 - 5)
26 + 4(1)
26 + 4 = $30
Thus, we conclude that the cost of 13 CDs would be $30

The nearest whole number the diameter of the circle is 5.0 cm.
<u>Given the following data:</u>
- Circumference of a circle = 15.4 cm
To estimate to the nearest whole number the diameter of the circle:
In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.
<h3>How to calculate the circumference of a circle.</h3>
Mathematically, the circumference of a circle is given by the formula:
<u>Where:</u>
- D is the diameter of a circle.
Making D the subject of formula, we have:
Substituting the given parameters into the formula, we have;
D = 4.90 cm
To the nearest whole number:
D = 4.90 ≈ 5.0 cm
