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 form $y = f (x)$ , 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:

$f (x) = x-0.2x$

The feasible region is shown in the picture above. The horizontal axis is the X axis.

If you now draw a family of lines parallel to $5x+4y=C$ through the region, increasing $C$, that is, the X-intercept, we will have the maximum value of $C$ when the line passes through the endpoint $(-2,6)$ .
