An advertisement reads all books 28 percent off a best-selling novel is originally priced at $18.99. About how much money will Gio save if he buys the novel on sale?

For this case we know that the original price is $18.99 and the discount for this case is 28% off.

So we can begin finding the 28% of the original price:

Discount = 18.99*0.28 = $5.3172

So then He would expect to save $5.3172 and the final price would be:

Final price = 18.99 - 5.3172 $ = $13.6728

Step-by-step explanation:

For this case we know that the original price is $18.99 and the discount for this case is 28% off.

So we can begin finding the 28% of the original price:

Discount = 18.99*0.28 = $5.3172

So then He would expect to save $5.3172 and the final price would be:

Final price = 18.99 - 5.3172 $ = $13.6728

28% of 18.99 is 5.2172

Because 18.99 * 0.28 = 5.2172 which can be rounded to 5.22

So Gio would save about $5.22.
