-8/7 is the correct answer.
        
             
        
        
        
ok so divide 1500 by 250 to determine how many boxes you need to by in 1 year
so that equals 6 then you multiply that by $30 to find the total cost of all the diapers per year so the is $180 per year and then multiply that by 3 to find the cost of all 3 years 
So the answer is you will spend $540 in total
 
        
             
        
        
        
G(x) would have to be -->7 units.
The relationship between f(x) and s(x) where s(x)=af(x-b)+z is that g(x) is f(x) stretched by the reciprocal of a, b is the liar (all x values go up if b goes down and visa versa), and it moves up z units. 
        
                    
             
        
        
        
The answer is 5/12 because 1/6 converts to 2/6 and 7/12-2/6 is equal to 5/12
