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?
28% is 28/100
And 1/100 of $18.99 is 18.99 c. Call it 19 c.
Therefore 28/100 of $18.99 is 28*19 c = 532 c = $5.32
So, Gio will save a little over $5.
The answer then is,
Option B - $6
