2 x 6x - 2 x 5y - 7
12x - 10y - 7
Ok well, first of all, you must do 12 x 2 because if Mike has twice as many of red marbles, (12 red) then you must multiply that by 2. So 12 x 2 is 24! Then Mike has 3 times as many of yellow marbles, so you do 24 x 3, which is 72! So the answer is A, Sandy is correct. Hope this helps! :)
Answer:

Step-by-step explanation:
From the question we are told that
The daily demand is 
The standard deviation is 
The service probability is 
The number of chips in the inventory is 
The number of days in his monthly is 
The lead time is 
Generally the number he should order (optimal order ) is mathematically represented as

Here
is the monthly standard deviation which is mathematically evaluated as

=> 
=> 
Also z-value for the 95% service probability from the z-table is 1.96
So

=> 
For the maximum order quantity k = 0
So

=>
=>
