A pair of $80 shoes is 25% off. A bar model splits the price into four 25% parts of $20, so the discount is $20 and the sale price is $80 − $20 = $60, checked by the 3 parts left (75%) being worth 3 × $20 = $60.

Transcript

What the lesson says

A pair of shoes costs 80 dollars.

The shoes are on sale at 25 percent off.

What is the sale price, the new price you pay?

Think of the full price, 80 dollars, as 100 percent.

25 percent is one quarter, so split the bar into 4 equal parts.

80 dollars divided by 4 is 20 dollars, so each part is 20 dollars.

The discount is the money taken off, which is one part, or 20 dollars.

To find the sale price, take the discount away from the full price.

80 dollars minus 20 dollars is 60 dollars.

Check with the bar: the 3 parts left are 75 percent, and 3 times 20 dollars is 60 dollars.

So the sale price of the shoes is 60 dollars.

To find a sale price, work out the discount and take it away from the price.
