Apen cost 20php each, if you buy more than 10pens you will be given 50percent discount on the next pens you're about to buy. mak
vredina [299]

Cost of pen = 20x  when x< 10

                              and

                      =10x when x>10

Let the number of pens bought be x.

So the total pen cost is 20x when the number of the pen is less than 10.

Now let's take that the number of pens bought is more than 10

So the pen will cost a 50% discount  

    50% of 20x

  = 20/100 × 20x

  = 10x

So the cost of the pen will be 10x when the number of the pen is greater than 10.

From this, we get to know that

Cost of pen = 20x when x<10

                              and

                       = 10x when x>10

To know more about the cost and prices refer to the link given below:

What is the y-intercept of the function f(x) = -3x<br> Ο<br> Ο<br> on who wire on<br> Ο<br> Ο
morpeh [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

f(x)=-3x

so

For x=0

substitute

f(0)=-3(0)=0

therefore

The y-intercept is the point (0,0)

Part 2) we have

f(x)=-3^x

so

For x=0

substitute

f(0)=-3^0=-1

therefore

The y-intercept is the point (0,-1)
