Answer 2

Answer: Our required answer is $0.13.

Step-by-step explanation:

Since we have given that

25 items purchased @ $21.25

So its unit price is given by

$\frac{21.25}{25}=0.85$

50 items purchased @ 36.00

So, its unit price is given by

$\frac{36}{50}=0.72$

80 items purchased @ 60.00

So, its unit price is given by

$\frac{60}{80}=0.75$

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.
