Find the unit price (price per bottle) 
$3.79 ÷ 6 = $.63 a bottle (approximately)
$4.50 ÷ 9 = $.50
$6.89 ÷ 12 = $.57 (approximately)

So your best bet is the 9 pack.  
You will find that sometimes your best value is not to buy the greatest amount of a product.

What are the steps on finding common denominators. PLEASE HELP
Dmitrij [34]

Step-by-step explanation:

to find a common denominator, you have to find a number that "works" with every other number.

for example, say you have

2/4 and 8/12

First you need to find the common factor between 4 and 12, so list all your fours

4, 8, 12, 16, 20

Now list all your twelves

12, 24, 36, 48, 60

to find the common factor you look at both your list of numbers and find one that's the same, sometimes it takes a long list of numbers to find the common factor, but you will run into one.

So by looking at our list we see that 4 and 12 share the common factor of 12. but since 8/12 already has a denominator of 12, we are going to leave it alone.

now think about what you would multiply 4 by, to get to 12. The answer is

4 x 3 = 12

to make the numerator correct, you multiply it by the same number you did 4, so since your faction is 2/4 you should do 2 x 3 = 6

now you have your answer,

2/4 and 8/12 turns into

6/12 and 8/12

and that's how you find it, let me know if you have questions :)

The table below shows the results of flipping two coins. how does the experimental probability of getting HH compare to the theo
marusya05 [52]
The correct answer is option B. i.e. the experimental probability is 3% greater than the theoretical probability<span>

The </span>theoretical Outcomes are: HH HT TH TT
 Then, the probability of getting HH = 1/4 = 0.25 = 25%

Now, Experimental Outcomes : <span>HH=28 HT=22 TH=34 TT=16
Total number of outcomes = 28+22+34+16 = 100
</span>Then, the probability of getting HH = 28/100 = 0.28 = 28%

Thus, <span>the experimental probability is 3% greater than the theoretical probability</span>

How to work this problem must show work. n-2
Leona [35]
I am only guessing that you mean:

(n-2)/-3<7  if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)

n-2>-21  add 2 to both sides

n>-19
