Question

Babaganoush’s electricity supply company charges him a fixed quarterly sum plus a rate per unit for electricity used. In the most expensive quarter last year (January to March), he used 2,400 units and his bill was $320. In the least expensive quarter (July to September), he used 800 units and his bill was $144. He is now adding extra insulation to his home which is expected to reduce his overall electricity consumption by 25%.
What can he expect his January to March bill to be next year (if there are no increases in overall tariffs)?

Answer 1

Answer:

14,848.25

Step-by-step explanation:

2400+800=3200

320+144=464

25                       3200            464

----                          ------             ----=               14,848.25

100                            x                x

25x3200x464 divided by 100

Hope this helped and have a great day!
