Question 1200364
.
<pre>
(a)  If 0 < x < 40,

     then the fine is calculated this way: it is the product of $25 and (40-x).

     So, if 0 < x < 40, then fine F(x) = 25*(40-x)  dollars.



     If 40 <= x <= 65,

     then there is no fine;  or, you can write F(x) = 0.

     So, if 40 <= x <= 65, then fine F(x) = 0  dollars.



     If 65 < x,

     then the fine is calculated this way: it is the product of $25 and (x-65).

     Again, if  65 < x, then fine F(x) = 25*(x-65)  dollars.



Now you have enough (the full instructions) to calculate everything in part (b).
</pre>

Make the remained calculations for part (b) on your own.


You can report me your results.


If you do, I will check it for you at no charge.
