Think firstA $20 book, and Ontario's 13% tax
Ontario adds 13% tax to the $20 book. What is 13% of $20?
Decide first, then press Next. Watch the bar: ten equal parts make the whole price.
A bar for the $20.00 price, cut into ten equal parts. The first part is shaded: 10% is $2.00. An enlarged strip shows that part cut into ten again, three of them shaded: 1% is $0.20, so 3% is $0.60. Then a longer bar: $20.00 plus $2.60 of tax, $22.60 in all. The last step asks about $40 skates.

The big idea
Ontario's 13% sales tax is 10% plus 3 × 1% of the price, added to the total.
In OntarioMost things have 13% sales tax, called HST. Some things, like basic groceries, have none. The shelf price does not show it; the till adds it.
Easy to get wrongA percent is not dollars: 13% of $20 is $2.60, not $13.
