This is a start:
=IF(AND(A1>=10000,A1<=20000),A1*15%,IF(AND(A1>20000,A1<=25000),A1*10%,"Your Entry"))
Reads as follows: If the price greater than 10000 and less than or equal to 20000 the A1 (which is the price of the car)*5%, If A1 greater than 20000 and A1 <=25000, then A1*10%.
Select an IF Function and then select the AND function - when you close the "AND" function you will get an "ERROR MESSAGE" window - just ignore it.
Then in the formula area put your cursor on the 1st IF statement and then, double click on the Fx icon - next to the formula box.
You can have up to seven (7) If statements.
If you need more than seven you might have to use a "LOOKUP" Function.
