Answer:
The answer is 358.01
Step-by-step explanation:
Given:
![3\times 10^{2}+5\times 10^{1}+8\times 10^{0}+1\times \frac{1}{10^{2}}](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E%7B2%7D%2B5%5Ctimes%2010%5E%7B1%7D%2B8%5Ctimes%2010%5E%7B0%7D%2B1%5Ctimes%20%5Cfrac%7B1%7D%7B10%5E%7B2%7D%7D)
Now, to solve first we crack the power notation then multiply and then do the addition:
![3\times 100+5\times 10+8\times 1+1\times \frac{1}{100}](https://tex.z-dn.net/?f=3%5Ctimes%20100%2B5%5Ctimes%2010%2B8%5Ctimes%201%2B1%5Ctimes%20%5Cfrac%7B1%7D%7B100%7D)
(The value of
is 10 and the value of
is 1.)
![=300+50+8+\frac{1}{100}](https://tex.z-dn.net/?f=%3D300%2B50%2B8%2B%5Cfrac%7B1%7D%7B100%7D)
![=300+50+8+0.01](https://tex.z-dn.net/?f=%3D300%2B50%2B8%2B0.01)
.
Therefore, the answer is 358.01 .
Answer:
the best value is two 50 ml bottles
Step-by-step explanation:
Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =
![45 + \frac{45}{2} = 67.5](https://tex.z-dn.net/?f=45%20%2B%20%20%5Cfrac%7B45%7D%7B2%7D%20%20%3D%2067.5)
We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !
then you can dived the volume of bottle with price ...
- the price of one ml is 0.675 in first State
![\frac{67.5}{100 } = 0.675](https://tex.z-dn.net/?f=%20%5Cfrac%7B67.5%7D%7B100%20%7D%20%3D%200.675)
- in the second state the price of one ml is
![\frac{55}{80} = 0.6875](https://tex.z-dn.net/?f=%20%5Cfrac%7B55%7D%7B80%7D%20%20%3D%200.6875)
then :
![0.675 < 0.6875](https://tex.z-dn.net/?f=0.675%20%3C%200.6875)
so the best value is two 50 ml bottles
