Jeans are on sale for 20% off the regular price.
7nadin3 [17]

Keywords:

<em>Function, variable, total cost, percentage, jeans </em>

For this case we have a function of the formy = f (x), where f (x)represents the total cost of buying a pair of jeans, considering that they are 20% below the regular price given by the variable x.

So, if the pair of jeans costs x, we look for 20% of x.

x -----------> 100%

? -----------> 20%

Where "?" represents 20% of x. So, we have:

? = \frac {20 * x} {100}\\? = 0.2x

Thus, 0.2x represents the reduction of the total cost of the pair of jeans

Then, the function that gives the total cost of the pair of jeans, with a reduction of 20% is:

f (x) = x-0.2x

Answer:

f (x) = x-0.2x

Option C
