Is it possible to do the following formal by Microsoft Office Excel 2003:
Products as following
If customer buy 10 parts the cost will be 5$ by parts
If take any number over 10 parts will be 5$ for first 10 and more will $4

Example if take 12 parts will be the price as following:
(10*5)+(2*4)=58
And this products price as following
0 part to 10 the price 5$
11 to 20 the price 4$
21 to 30 the price 3$
More than 30 the price will be 2$

Example

Customer buys 33 parts so we charge him as following

0 -10 we charge him 10 * 5 $= 50 $
11 €“ 20 10 * 4 $= 40$
21 -30 10 * 3$ = 30$
31 to 33 3 * 2$ = 6

So the total charge will be 126
