Answer:
(a) $248.285
(b) $249.441
(c) I will prefer to buy the television from online store.
Step-by-step explanation:
The manufacturing price of a television is $170.
(a) The online retailer charges a standard makeup of 27% and an additional 15% charge for shipping and tax.
Therefore the final price will be $](https://tex.z-dn.net/?f=%5B170%281%2B%5Cfrac%7B27%7D%7B100%7D%29%5D%281%2B%5Cfrac%7B15%7D%7B100%7D%20%29)
= $(170 × 1.27 × 1.15)
= $248.285
(b) Now, the superstore has makeup of 34% and then 9.5% charges for state tax.
So, the final price becomes $](https://tex.z-dn.net/?f=%5B170%281%2B%5Cfrac%7B34%7D%7B100%7D%20%29%5D%281%2B%5Cfrac%7B9.5%7D%7B100%7D%29)
= $(170 × 1.34 × 1.095)
= $249.441
(c) So, I will prefer to buy the television from the online store because the final price is less and also the shipping charges are included in the final price. (Answer)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
 
        
             
        
        
        
-6(2x - 4) =  -6*(2x) -6*(-4) = -12x + 24
-(12x - 6) + 18 = -12x + 6 + 18 =  -12x + 24
-3(4x - 3) + 15  = -3*(4x) -3*(-3) + 15 = -12x + 9 + 24 = -12x + 24
-4(3x + 6)
= -4*(3x) -4*(6) = -12x -24
All the expressions gave the same answer as -12x + 24, except for the last expression.
So, -4(3x + 6) 
is not equivalent to the others.
