A pair of pants regularly costs $68. The pants are on sale for 45% of the original price. How much will the discount be?
Novay_Z [31]

The discounted amount of pair of pants is $37.4

<u>Solution:</u>

Given, A pair of pants regularly costs $68.  

The pants are on sale for 45% of the original price.  

We have to find that how much will the discount be?

Now, <em>discounted amount = original price – sold price </em>

Discounted amount = original price – 45% of original price

Discounted amount = $68 – 45% of $68

\begin{array}{l}{=68-\frac{45}{100} \times 68=68\left(1-\frac{45}{100}\right)=68 \times \frac{100-45}{100}=68 \times \frac{55}{100}} \\\\ {=\frac{3740}{100}=\$ 37.4}\end{array}

Hence, the discounted amount is $37.4
