Answer: 7 packs of gum.
Step-by-step explanation: 
If the total amount of the purchase is $8.82 and the individual price is $1.26, to find out how many packs Kareem purchased, we need to divide the total amount spent ($8.82) by the amount of each pack ($1.26), so:
8.82 ÷ 1.26 = 7
So, Kareem bought 7 packs of gum.
 
        
             
        
        
        
Answer:
A - B  =  [  -1  3  ]
              [ -6  2  ]
              [ -4 -10 ]
Step-by-step explanation:
Since Matrix A and Matrix B have the same size, then we can simply perform the operation of subtraction on each position within the matrices to get the resulting subtracted matrix. 
A =  [  4  7  ]              B =  [  5  4  ]
       [ -3  8  ]                     [  3  6  ]
       [ -5 -2  ]                    [  -1  8  ]
A - B  =  [ (4 - 5)  (7 - 4) ]
              [ (-3 - 3) (8 - 6) ]
              [ (-5 - -1) (-2 - 8) ]
A - B  =  [  -1  3  ]
              [ -6  2  ]
              [ -4 -10 ]
Cheers.
