Answer 1

Answer: Our required answer is $0.13.

Explanation:

Since we have given that

25 items purchased @ $21.25

So its unit price is given by

`(21.25)/(25)=0.85`

50 items purchased @ 36.00

So, its unit price is given by

`(36)/(50)=0.72`

80 items purchased @ 60.00

So, its unit price is given by

`(60)/(80)=0.75`

So, Highest unit price for the whistles will be $0.85

Lowest unit price for the whistles will be $ 0.72

Difference between the highest unit price and lowest unit price for whistles will be

`0.85-0.72=\$0.13`

Hence, our required answer is $0.13.
