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:
