Moana’s water company charges her a fixed quarterly sum plus a rate per unit for water used. In the most expensive quarter last year (January to March), she used 2,200 units and her bill was $275. In the least expensive quarter (July to September), she used 600 units and her bill was $167. She is now using a new filtration device which is expected to reduce her overall water usage by 20%. What can she expect his January to March bill to be next year (if there are no increases in overall tariffs)?

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
