Excel - IF Function - Adding a $1 to every number over target

Question

I am trying to write a formula that will add a $1 payout to every unit sold over a target number.  For example, if someone has a target to sell 22 cases of a product and they sell 22, they will receive $100.  For every case sold over 22, I want to add an additional $1 payout to the $100.  Attached is what I have so far.  I know how to set it up so they can get the $100 when they hit their target, I just can't figure out how to add the additional $1 to every case sold over their goal.  Also, if they don't hit their target, they will get $0.

Answer 1

=IF(D10>=C10;100+(D10-C10);0)

Answer 2

=if(d10>=c10,100+c10-22,0)
