Calculate the Electricity bill problem using conditional statement IF else pseudo code algorithm


Write a pseudo code, Features and represent the information on a flow chart which reads units of electricity and usage type to calculate the electricity bill.
Bill=units*rate
Unit used (u)
Residential rate
Commercial rate
0 < units <= 200
0.8
0.6
200 < units <= 999
0.7
0.3
Above 999
0.5
0.2
Read a units
Read a usage type
IF  usage_type equal “Residential”
      IF units >0and units <=200   THEN
             Bill= units*0.8
     ELSE IF units >200 and units <=999   THEN
                     Bill= units*0.7
                ELSE
                     Bill= units*0.5
               END IF
     END IF
ELSE
         IF units >0and units <=200   THEN
             Bill= units*0.6
         ELSE IF units >200 and units <=999   THEN
                     Bill= units*0.3
                   ELSE
                     Bill= units*0.2
                  END IF
        END IF
