Question

Seth is trying to find the unit price for a package of blank compact discs on sale at 10 for $5.49 . Find his mistake and correct it

Answer 1

The unit price of the disk is $0.549

Unit price of goods

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
