Answer: 14.29 or rounded up to 15%
Step-by-step explanation:
525 - 450 = 75
You need at least $75 off the price to have enough money.
75/525 = x/100
Solve for X
75 * 100 = 7500
7500/525 = 14.2857143
If answer should be a whole percentage you would need the discount to be 15% in order to not fall short on funds.
 
        
             
        
        
        
Answer:
x = 2
y = -8
Step-by-step explanation:
9x−2y=34 -------------------(I)
5x+2y=−6 -------------------(II)
Add equation (I) & (II) and so y will be eliminated and we could find the value of x.
(I)      9x -  2y = 34
(II)     <u>5x  + 2y = -6</u>   {add}
        14x         =   28
                  x = 28/14
x = 2
Plug in x = 2 in equation (I)
9*2 - 2y = 34
 18 - 2y = 34
      -2y = 34 - 18
     -2y = 16
         y = 16/-2
         y = -8
