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.
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.
To calculate the total charge, we need to add the fixed charge of 800 naira to the charge proportional to the number of units of call.
Let's calculate the total charge for each case:
a) For 80 units:
Fixed charge = 800 naira
Charge per unit = 2 naira
Total charge = Fixed charge + (Number of units × Charge per unit)
Total charge = 800 + (80 × 2)
Total charge = 800 + 160
Total charge = 960 naira
b) For 150 units:
Fixed charge = 800 naira
Charge per unit = 2 naira
Total charge = Fixed charge + (Number of units × Charge per unit)
Total charge = 800 + (150 × 2)
Total charge = 800 + 300
Total charge = 1,100 naira
c) For 782 units:
Fixed charge = 800 naira
Charge per unit = 2 naira
Total charge = Fixed charge + (Number of units × Charge per unit)
Total charge = 800 + (782 × 2)
Total charge = 800 + 1,564
Total charge = 2,364 naira
Therefore, the total charges would be:
a) 960 naira
b) 1,100 naira
c) 2,364 naira
