71.4 and to check just multiply 71.4 times 5 and it'll get 357
        
             
        
        
        
The answer is 24 as it's the smallest number given that is divisible by both 6 and 8.
        
                    
             
        
        
        
48x0.2= $9.6
$48-9.6=$38.40 Her friend is incorrect. 
40/48 =0.83 or about 83% So, in this case she only got 17% off. :)

Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7     Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y =  -11.
