During the summer, a property owner will pay $24.72 plus $1.32 per hcf for conservation usage. the bill for conservation usage would be between or equal to $31.32 and $52.12. how many hcf can the owner use if she wants her usage to stay in the conservation range? enter truncated values for answers. example: enter 8.93 as 8 and 6.34 as 6.

The owner can use between 5 and 20 HCF to stay in the conservation range

Step-by-step explanation:

Let's calculate the number of HCF, this way:

Lower value = (31.32 - 24.72)/1.32 = 6.60/1.32 = 5

Upper value = (52.12 - 24.72)/1.32 = 27.4/1.32 = 20.76 = 20 as truncated value

The owner can use between 5 and 20 HCF to stay in the conservation range
