IF THEN ELSE Crystal Reports EXPRESSION to SSRS EXPRESSION

I have the following Crystal Reports expression and I want to be able to translate it SSRS expression:

IF LEFT({WorkflowCode.WorkflowCode},3) = 'DEL' THEN
   IF ({WorkOrder_vw_Totals.Charges} - 50.00) <= 0.00 THEN
      0.00
   ELSE
      (({WorkOrder_vw_Totals.Charges} - 50.00) *  {Parameter} / 100)
Else
   (({WorkOrder_vw_Totals.Charges} - {@DisposalCost})* {?Parameter}) / 100

Thank you in advance for the help!
