f(x) = 0.2x - x
f(x) = x - 0.2x

Keywords:

Function, variable, total cost, percentage, jeans

For this case we have a function of the form, where 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:

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:
