Answer 1

Answer:

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

$(21.25)/(25)=0.85$

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.

What two numbers multiply to -84 and add to 5

Answers

12 & -7

multiplied = -84
added 12 + -7 = 5

From the top of your head you know 12 * 7 = 84.

But let's rearrange it to suit.

12 * - 7 = -84

12 + (-7) = 12 - 7 = 5.

So the two numbers are 12 and -7.
