Answer:
A) None
Step-by-step explanation:
1) 
shoudnt neccesarily be a factor of nst, for example, if s = 3, t = 4, and n = 12, then both s and t are factors of n, but 
is not a factor of nst = 144.
2) 
shoudnt neccesarily be a factor of nst. Let s be 4, let t be 6, and let n be 12. Then n is a factor of both s and t, but 
is not a factor of nst = 12*24. In fact, it is a greater number.
3) Again, s+t isnt necessarily a factor of nst, let s be 2 and t be 3. Then both s and t are factor of n = 12. However 5 = s+t is not a factor of nst = 72.
So, neither of the three options is guaranteed to be a factor of nst. In fact, for s = 4, t = 6, and n = 12, none of the three options are valid.

These two claims about markup and margin are <u>equivalent</u> because they discuss differently the same issue.
<h3>What are markup and margin?</h3>
A markup is a profit percent added to the cost price to determine the selling price. Thus, markup relates the percentage of profit to the cost price.
The profit margin relates the percentage of profit to the selling price.
<h3>Data and Calculations:</h3>
Selling price = 100%
Profit margin = 25%
Cost price = 75% (100% - 25%)
Markup = 33% (25%/75% x 100)
Thus, these two claims about markup and margin are <u>equivalent</u>.
