<h3>Unit price of goods</h3>
The unit price of goods are the price of one portion of the goods in question.
From the given question, a package of blank compact discs on sale at 10 for $5.49, this can be expressed as;
10 disc = $5.49
The unit price of the disc is the price of just one of the disc. The unit price is expressed as;
1 disc = x
Find the ratio
10/1 = 5.49/x
Cross multiply
10x = 5.49
Divide both sides by 10
10x/10 = 5.49/10
x = $0.549
Hence the unit price of the disk is $0.549
