1)When the value of kilowatt hour increases the value of amount due increases as well
2) The formula y=kxn y = k x n is used for direct variation. The value k is a nonzero constant greater than zero and is called the constant of variation. In this case, k=0.16 and n=1
3) Appliances
Switch off your appliances when they're not in use
Your TV, computer, microwave and even some washing machines have a 'standby' mode, which means they're still using energy even when they're not in use. Turn them off at the power point to reduce their energy consumption (you don't have to unplug them).
Buy appliances with a good energy rating
The more stars, the more savings – but think about size first. Often it's easier for a larger model to be more energy-efficient (and therefore have more stars) than a smaller one. However, since it's bigger, its overall energy consumption is usually higher.
Pick the right washing machine
Although they usually cost more to buy, most front-loader washing machines save you money over time and are kinder to the environment because they use less power, water and detergent than top loaders. See our washing machine reviews for the most energy-efficient models.
