Answer:
The powdered drink mixes is a better price per gallon on lemonade produced.
Step-by-step explanation:
The powdered drink mixes is a better price per gallon on lemonade produced because of the following reasons listed below:
The cost price to produce lemonade for the powdered mixes goes for $1.79 each for 2 gallons which is lesser and cheaper and much more affordable compared to cost of preparing the lemonade from fresh lemons
The cost of buying fresh lemons which is calculated to cost
$0.39 for 1 lemon which means for 10 lemons, the cost would be
10 × $0.39 = $3.9
1 pound of sugar cost $2.99
The total cost price would be
$3.9 + $2.99
= $6.89
When we compared the both prices and check the calculation shown above, we can see that the powdered mixes is a much better option and much better price per gallon of lemonade purchased.
Answer: <u>$22.05</u>
Step-by-step explanation:
We know,
1 gallon = $1.47
Then,
15 gallons = $1.47 * 15 = $22.05
C. at least i got it right
Answer:
The correct answer is B,
Step-by-step explanation:
Since the higher value of z's power, is 4, an even number, and the second number is negative, we can think that this binomial is made of a difference of squares, so that is what we are going to factorize.
First, extract the common number (if any), the number 2, we have now>
![2*(z^{4}-1)](https://tex.z-dn.net/?f=2%2A%28z%5E%7B4%7D-1%29)
This is convenient since "1" is a wonderful number that has this feature>
No matters what n's value is,
so the first equation
can be written as ![(2*(z^{4}-1)=2*((z^{2})^{2}-1^{2})=2*(z^{2}-1)*(z^{2}+1)](https://tex.z-dn.net/?f=%282%2A%28z%5E%7B4%7D-1%29%3D2%2A%28%28z%5E%7B2%7D%29%5E%7B2%7D-1%5E%7B2%7D%29%3D2%2A%28z%5E%7B2%7D-1%29%2A%28z%5E%7B2%7D%2B1%29)
The later termn, can also be factorized, using the same as befre.
![(z^{2}-1)=(z-1)*(z+1)](https://tex.z-dn.net/?f=%28z%5E%7B2%7D-1%29%3D%28z-1%29%2A%28z%2B1%29)
Remember that ![z^{4}=(z^{2})^{2}](https://tex.z-dn.net/?f=z%5E%7B4%7D%3D%28z%5E%7B2%7D%29%5E%7B2%7D)
