I'm pretty sure that it's the first one: direct variation; y=4x.
        
             
        
        
        
Answer:
The answer is B. -7

Answer: i cant graph  but polt 0,4 on the y axis the go up 1 to the right 8
Step-by-step explanation:
 
        
             
        
        
        
 For Times Square magnets, we have that the price of each magnet is 2 dollars / magnet, there are 4 magnets / set, and Tom buys 12 sets. For Statue of Liberty magnets, the price is 3 dollars / magnet, there are 5 magnets / set, and Tom buys 12 sets
We can make a table of these values: 
 
Magnets          Price ($$/magnets)        Set Size (magnets/set)         Quantity (sets)
T.S.                2                                  4                                        12
S. of L.           3                                  5                                        12
 
Now, we can use the formula 
 
Total Cost = Number of Magnets Bought * Price = (Quantity * Set Size) * Price
 
So we see that
 
Cost of T.S. magnets = Quantity * Set Size * Price
                               = 12 sets * 4 magnets * 2 dollars = $96
                                                       set          magnet
 
Cost of S. of L. magnets = Quantity * Set Size * Price
                                   = 12 sets * 5 magnets * 3 dollars = $180
                                                           set          magnet
 
So the total amount spent was $96 + $180 = $276.
