(2 1/2 x 24)/6 = 10 pounds of apple will make serve 24.
Therefore, she will use 10 pounds of apples.
        
             
        
        
        
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
 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.
 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
 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.
 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.
 
        
             
        
        
        
Answer:
Total cost of Mark's board is $3.75.
Step-by-step explanation:
We are given the following in the question:
Length of wooden board = 

Unit cost of board = $0.50 per foot
Total cost of board =

Thus, total cost of Mark's board is $3.75.
