Answer:

Table of charges:

KWh 0 5 10 15 20

Basic charge (cents) 11.60 11.60 11.60 11.60 11.60

Charge for first 10 kWh (4.59cents) 0 22.95 45.90 45.90 45.90

Additional usage above 10 kWh 0 0 0 48.55 97.10

(9.71 cents)

Total (cents) 11.60 34.55 57.50 106.05 154.60

cost (dollar) 0.12 0.35 0.58 1.06 1.55

KWh 25 30 35 40

Basic charge (cents) 11.60 11.60 11.60 11.60

Charge for first 10 kWh (4.59cents) 45.90 45.90 45.90 45.90

Additional usage above 10 kWh 145.65 194.20 242.75 291.30

(9.71 cents)

Total (cents) 203.15 251.70 300.25 348.80

cost (dollar) 2.03 2.52 3.00 3.49

Step-by-step explanation:

a) Data:

Basic charge = 11.6 cents (0.116)

Charge for the first 10 kWh = 4.59 cents (0.0459)

Charge for additional usage above 10 kWh = 9.71 cents (0.0971)

b) Each kWh consumed or not attracts the basic charge of 11.6 cents. The first 10 kWh consumed is billed at 4.59 cents, while the additional kWh consumed is charged at 9.71 cents. The charge per consumption is first totaled in cents before being converted to dollars by dividing by 100.
