<em>Function, variable, total cost, percentage, jeans </em>
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:
Answer:
Option C
The expression can be simplified to a polynomial of degree 2.
<h3>How to simplify the expression?</h3>
Here we have the expression:
We can directly simplify this by taking the variable as common factor:
This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.
