Question from tom, a student:

a TV can be purchased for $278 normally is $328. what is the percent of the present cost of this TV will you be saving?

Hi Tom,

To my this is a very unnatural question.

The saving is $\$328 - \$278 = \$50.$ $\$50$ as a percentage of $\$328$ is $\large \frac{50}{328} \normalsize \times 100 = 15.2\%.$ So I would say that the price is marked down by $15\%.$ The question asks for you to calculate the $\$50$ as a percentage of $\$278.$
