A telephone company makes up it's monthly bills as follows:a fixed charge of 800 naira plus a charge proportional to the number of units of call on the telephone.if it charges 2 naira per unit of call, calculate the total charge on a=80 units,b=150 units,c=782 units.

Answer 1

To calculate the total charge, we need to multiply the number of units by the charge per unit and add the fixed charge.

a) For 80 units:
Total charge = (80 units * 2 naira per unit) + 800 naira
Total charge = 160 naira + 800 naira
Total charge = 960 naira

b) For 150 units:
Total charge = (150 units * 2 naira per unit) + 800 naira
Total charge = 300 naira + 800 naira
Total charge = 1100 naira

c) For 782 units:
Total charge = (782 units * 2 naira per unit) + 800 naira
Total charge = 1564 naira + 800 naira
Total charge = 2364 naira

Therefore, the total charges on a=80 units, b=150 units, and c=782 units are 960 naira, 1100 naira, and 2364 naira, respectively.
