Answer:
The pseudocode is as given below in the explanation while the flow diagram is attached herewith
Step-by-step explanation:
The pseudocode is as follows
input cust_name, num_texts
Set Main_bill=5 $;
if the num_texts is less than or equal to 60
Excess_Charge=0;
If the num_texts is greater than 60 and less than or equal to 200
num_text60200 =num_texts-60;
Excess_Charge=0.1*(num_text60200);
else If the num_texts is greater than 60
num_texts200 =num_texts-200;
Excess_Charge=0.25*(num_texts200)+0.1*(200-60);
Display cust_Name
Total_Bill=Main_bill+Excess_Charge;
Total_Bill_after_Tax=Total_Bill*1.12;
