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
