Question

A coat usually on sale for $150 is on sale at 25% off. What is the sale price of the coat?

Answer 1

At $100    off   $25
    $1         off    $\frac{25}{100}$
   $150      off     $\frac{25.150}{100}$
                        
                        =$ 37.5

new price= 150-37.5=112.5

Answer 2

$112.50. 25% is .25 and .25 times 150 equals 37.50, so then you subtract 37.50 from 150 and you get $112.50.
