5 STARS!!!! PLS HELP

Answer 1

Correct answer is:- standard price for first 200 boxes is 8$ and the amount spent on the pens offered at discounted rate is 1800$.

Solution:-

We are given that for first 200 pens, there is a standard price. Let the standard price be y.

So if some one purchases pens fewer than 200 then amount to pay =200y.

If  number of boxes is more than 200, then each box over 200 is given at a discounted rate. Let the discounted rate be d.

Then price of the x boxes if x>200 is (standard price * 200)+( x-200)*d

                                                          = 200y+(x-200)d

Hence price of each box = $\frac{200y+(x-200)d}{x}$

If we compare above equation with given equation,

200y=1600 and (x-200)d=6(x-200)

 y=8 and d=6.

a)Hence standard price for first 200 boxes=8$

And discounted price per box which is over 200 boxes=6$

b)If the customers order 500 boxes of pens then the amount spent on pens offered at discounted rate = (number of boxes over 200)*(discounted rate)

                               =(500-200)*6=1800$
