Answer:
MWQ is 143 mg
Step-by-step explanation:
given data
sensitivity requirement (SR) = 6.0 mg
maximum error = 4.2%
to find out
MWQ
solution
we know here MWQ formula that is
MWQ = 
................1
so here error is 4.2 % = 0.042
put here all these value in equation 1 we get
MWQ =
MWQ = 
MWQ = 142.857 mg
so MWQ is 143 mg
6% = 0.06
multiply:
62900*0.06 = 3,774 ( Would be the amount of increase)
add:
62900 + 3774 = 66,674 (would be the new total)
Step-by-step explanation:

Option C is the correct answer
Answer:
The options are not shown, so i will answer in a general way.
Let's define the variables:
h = number of hats
m = number of mugs.
We know that a total of 1000 items were ordered, then:
h + m = 1000
We also know that we have 3 times more mugs than hats, this can be written as:
m = 3*h
Now we have the system of equations:
h + m = 1000
m = 3*h
To solve these, we usually start by isolating one of the variables in one equation and then replace that in the other equation, but in this case, we already have m isolated in the second equation, then we can replace that in the first equation to get:
h + m = 1000
h + (3*h) = 1000
Now we can solve this equation for h, and find the number of hats ordered.
4*h = 1000
h = 1000/4 = 250
There were 250 hats ordered.
