}

Algorithm

Start

Read name, units consumed as units

charge = 100

if units is <= 100 then 

compute charge = charge + units * 0.8 

else If units > 200 and units < 300 then 

compute charge = charge + 200 * 0.8 +(units – 200) * 0.9 

else 

compute charge = charge + (0.15*charge) 

Display name, units, charge

Stop
