Answer:
£325
Step-by-step explanation:
She paid £276.25 which is 85%
Divide 276.25 by 85 which is 3.25
3.25 is 1%
Multiply 3.25 by 100 to get the full Price 
3.25 x 100 = £325

Answer:
   D
Step-by-step explanation:
Solve x = f(y) for y.
   x = ∛(y/9) -4
   x +4 = ∛(y/9) . . . . . add 4
   (x +4)³ = y/9 .. . . . . cube
   9(x +4)³ = y . . . . . . multiply by 9
The inverse function is ...
   f⁻¹(x) = 9(x +4)³ . . . . . matches the last choice
 
        
             
        
        
        
Answer:
The median grade would be 89
Step-by-step explanation:
To find the median, first put the numbers all in ascending order. 
79, 80, 86, 92, 95, 96
Now isolate the middle term or terms. Since there is an even amount of numbers, we pick the two in the middle. To find the median, we take an average of those terms. 
(86 + 92)/2 = 89
 
        
                    
             
        
        
        
I=PRT, P=$1600 R=3% T=1yr 
=1600x(3/100)x1
= $48.00
