What is the answer meyn?
Alexandra [31]

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

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

  • in the second state the price of one ml is

\frac{55}{80}  = 0.6875

then :

0.675 < 0.6875

so the best value is two 50 ml bottles

A student wants to save at least $5000 for college. She begins with a savings account set up by her parents containing $2,500. E
Tamiku [17]

Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of  5000 dollars needed for college.

Step-by-step explanation: Im not good with equations but here  we go.

First: AS we know the account already had 2,500, and every month she deposits 50$.

What we can do is to divide 2,500 divided by 50 which will be 50.
